Hi!

You could consider adding PHP functionality as you are already running apache. There are loads of galleries for PHP out there on the web which should be much or less straight forward to install

I don't want a gallery. I said that. I don't want to have to manage a gallery. I don't want to have to install a RDBS. I don't need to comment. I don't need to kow the exif.

I just want to see the thumbnails so I can tell which photos I want to download onto my tablet to process there.

I DON'T WANT A GALLERY ! ! !

Actually, you DO, you just don't want to manage one, while at the same time you are demanding some of the functionality of a gallery without the commenting crap. Your best bet is to automate the creation of thumbnails and linking them into a index page so that you can do it once and forget about it. I ran into this same problem when I moved multiple gigabytes of family photos to a NAS box. They are all of a sudden hard to find visually. Even with gigabit ethernet browsing and trying to force Dolphin to show previews is horribly slow. Windows Explorer will do it, but not quickly. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It would be better to put the thumbnails in a second directory: thumbs/$1-th and it would be wiser to make the thumbs much smaller, under 500x500, because all of this has to be transmitted across the net to his tablet.

That seems crazy to me. Why would I go to a separate directory ... And those would still be viewed in ftp-mode.

Also that bit you mentioned "Builds an html page", how is that done? Isn't that the hardest part?

Please read the URL I keep sending. Its not a HTML page you want but HTML streams to the web interface of the client. The script at that URL generates such a stream. All dynamic and all dynamically picking up on the image files, even if they are dynamically added to. No need to generate a directory of thumbnails. Personally I'd use a <ul>..</ul> wrapper and have the items <li> tagged, but that's me. Bandwidth? I'm in the next room and there's no-one else using it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

sure I understood what you want. And believe me you can achieve this easily with PHP. I'm a developer for almost ages. But I can't imagine you'll get a satisfying solution when you reject any suggestions from the list instead of actively helping to develop an idea.

Just browse the web and get some inspiration. If you have trouble setting it up, you may want to ask and I'd be happy to help out.

I've browsed the web and seen at least a dozen 'possibilities'. For reasons I think I've made clear I rejected to ones that were clearly 'gallery' as in 'web site for showing off your photographs'. I have one of those of my own as an adjunct to my blog and don't use it much because it requires so much setting up on a step-and-repeat basis. And its not congruent with the use-case I'm trying for here. If my came has a 10" screen that would be fine, I'd never download! But that's not the case so I need to get the photos to the computer and selectively to the tablet to use as a display. I can do _some_ manipulation on the tablet. I can't bring all my peers and managers home to look at my screen and I can't go on site to compare 'then and now' photographs. Yes my tablet has split screen capability. Tablet are wonderful 'mobile' devices for us in the field. But their cameras are very deficient. Image processing software is good, but cameras are lousy. Be that as it may .... The article I referred to describes a CGI script that, with a bit of modification described in a later article http://www.askdavetaylor.com/create_apache_image_browser_script/ and http://www.linuxjournal.com/article/9622 does just what I want. But I can't get it to work. The author says <quote> Turns out you can do just that with a simple shell script named as index.cgi in the images directory (well, you might have to slightly tweak your httpd.conf configuration, but fundamentally it should be easy). </quote> Well I have that script by that name in my photographs directory and tweaked the httpd.conf to include user_mod and added the "Options ExecCGI" and ... It doesn't work. I'm far from an Apache guru. I can write a fair bit of html and can maintain a bit of javascript, but making this 'run' is beyond me. I have a specific use case, and it is NOT to run a gallery that can only be viewed on my home LAN. It is to identify the images to download to my tablet without actually downloading them. The 'ftp-mode' interface makes that latter a necessity. I'd appreciate some help getting a shell script as 'index.cgi' to work and getting it to work all the way down the photographs hierarchy rather than just the top level. I've referred to this article which I found by googling and trying out things that didn't work (like one based on dynamic light-table) four times now. I think it matches the very limited and focused use case I have. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

right now the problem is only: "how to run a cgi from apache"

tutorials are here

http://httpd.apache.org/docs/2.2/howto/cgi.html

to solve the OP problem, first we have to see why apache is not running cgi. the cgi of the OP is a bash script. The example in the apache page is perl, so may be begin to look at the very apache example: #!/usr/bin/perl print "Content-type: text/html\n\n"; print "Hello, World."; writing this very script here http://dodin.info/essai/th/test.pl it works. Good, so at least the OP can write his script in perl :-(. Then I tried an other bash script found on the net and it worked. What do not seems to work is bash loops. The following script http://dodin.info/essai/th/image.sh do (at time of writing) print Hello world end but the loop is ignored. Other syntax makes the "end" to be also ignored #!/bin/bash echo "Content-type: text/html" echo "" echo '<html>' echo '<head>' echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">' echo '<title>Hello World</title>' echo '</head>' echo '<body>' echo 'Hello World' for name in *.jpg do echo “<img src=$name>" "<br />" "$name" "<br />”; done echo '<br />' echo 'end' echo '</body>' echo '</html>' exit 0 I'm sure somebody will point out the error :-) thanks jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Anton, with all the replies in this thread, I guess you've worked out a solution by now? If not, I find thumbnails are most easily generated on the fly with imagemagick.

Anton, with all the replies in this thread, I guess you've worked out a solution by now? If not, I find thumbnails are most easily generated on the fly with imagemagick. If you're still looking, I can probably dig up some working code+config.

It took a little while, but I found this:

http://gallery.jessen.ch/

It's made up of two php files - index.phtml and makethumb.php, plus an apache rewrite config.

http://gallery.jessen.ch/verysimplegallery.tar.gz

Further instructions - - you need ImageMagick installed, I use 'convert' to create the thumbnails. - you need a working php installation, the scripts are php - you need apache module rewrite loaded - /index.phtml just lists whatever JPG files are in the same directory - you need to create a directory "tn/" with owner = wwwrun (or whichever userid your apache uses).

Once again, I don't want a full blown gallery. I don't want to have to zoom down on the images, I just want thumbnails.

Kong and Dolphin are opening the file for you, and either extracting the thumbnail that was built into the JPeg file or creating them on the fly. This is all very fast in the same machine, but once those images are stored across the room in a different machine Kong and Dolphin have enough sense to stop doing that on the fly because the bandwidth requirements become ridiculous.

That's interesting but I'm not accessing the files from my tablet in Konq/Dolphin.

But I've never gotten thumbnails from a web browser without them being separate files. I distinctly remember when I used to do this that there was a script that would create a thumbnails sub-directory in every photos directory which contained nothing but thumbnails, and a file called index.html, which linked the thumbnails to the actual photos.

The example reference I gave was a CGI shell script. http://www.askdavetaylor.com/create_apache_image_browser_script/ Let me quote #!/bin/sh echo “Content-type: text/html” echo “” for name in * do echo “<img src=$name><br />$name<br />” done exit 0 Now that really should be '*.jpg' :-) So I put that in ~/Photographs, made it executable and tried setting up ExecCGI for /home/*/public_html. I agree its a poor script, there needs to be something to limit the size :-) But why shouldn't it work? The point here is that there really isn't a need to generate thumbnails in a separate location. This is not a gallery application. Resource intensive? I don't care. When I'm doing this I'm not doing anything else on the server. And its really just a single user machine.
