User blog comment:JaseyJasee/Templates Changing pictures on Category pages/@comment-8-20150813010018

Hi,  The best place to ask questions like this is on the forums :) There are more people there who look for this sort of question to answer.

I think, though, that the problem of the template image showing in categories has gone. It just needed some time for the cache to catch up.

As for how you can add an image to the template without it being used in categories - I'm not totally sure, but I think there is a size limit on what images are used in categories. Try adding a smaller image and see if that helps.
