Hi, I updated my version of firefox to the latest version 42.0-2.1-x86_64 from earlier versions, and jpeg pictures won't render on a web page.
To troubleshoot the problem, I downgraded the version to 38.4.0-1.1-x86_64 and the jpegs will render again on a web page.
Any ideas why this is happening and how to fix it in the later versions?
Firefox doesn't contain code to render images. It uses cairo and libgdk_pixbuf which eventually hand the job to libjpeg or maybe libopenjpeg. So make sure you have the latest versions of those libraries.
All versions of the programs (libs) you have mentioned are the highest available version as presented in yast.
To find out why it's broken, download one of the broken images and use a local image viewer or another browser to examine the image. Tools like gimp and ImageMagick might also help.
Not exactly sure what I am specially looking for in gimp, but the image opens normally in gimp.
Note that it's possible that someone injected malicious code into those images which breaks rendering on Linux (as it should). Try to upload the image to https://www.virustotal.com/ and see what they say.
I uploaded one of the images on the webpage to https://www.virustotal.com and it gives it a solid 100% pass, no virus present. When I have the latest (or later "higher") version of Firefox installed, the place where the jpegs would normally open as pictures on the webpage are just open boxes. If I right click on the empty box and select "Open Image", then Firefox opens just the image as a subsequent page with nothing but the image present on a black background. When I select back to the original webpage, the browser just shows the empty box again where the picture would normally be displayed. Just to make it clear, by writing "the jpeg isn't rendering on the webpage," I am saying that there is just an empty box displayed where the picture would normally be displayed.
