My question is in respect to mailing images. What is the best way in linux to compress a jpg file, I apppreciate that there are various programs which will compress files or pack files into a zipped file, however this is for my wife who is less versed in most things technical.
Compressing to zip is not practical, because jpeg images are very compressed already. However, you can use a low compression level to put all the files on the same archive, be it zip, tar, etc - by the way. you can create tar.gz archives with the "text gui" mc, midnight comander (similar to the old Norton Comander for dos). On the other hand, for emailing it might be preferable not to do so, because as .jpg the images are directly visible on emails. Just remember not to send big emails - a 1 MB email can be very problematic for people using modems on noisy lines, for example.
Is there a simple method of reducing the size of a jpg file using Gimp or another image software package that will enable her to save the image as a smaller file (jpg) and send it via email still in jpg format?
- Reduce pixel count - Reduce number of colours - this doesn't work for jpg. - Reduce quality. In gimp it is click and shoot. Program "convert" is much faster for a list of similar images - command line, you know ;-) -- Cheers, Carlos Robinson
