Sure, why not - we have changed the image formats that we use internally. Also, we're not supporting adding non-GOG games to Galaxy in any way, I have only informed Taro94 that we'll be doing the change.
Thank you for taking the time to reply. I have checked the image files and dimensions in official GOG-approved games and the files I have created for non-GOG games are the same. My "resources.json" file and my "goggame-XXXXXXXXXX.info" file are formatted identically as well. Yet, with the new Galaxy update, all of my custom images have vanished. Is there any advice you can give me on how to make them visible in Galaxy again?
As skeletonbow mentioned - in-Galaxy browser caches (with a limit and algorithm for that) images to make everything load faster and not use your bandwidth too much. I'll do an extra check there.
I can appreciate that, but I am seeing folders for games I have never even looked at before. I'm all for reduced load times, but I think the current version of the algorithm might need to be reigned in a little bit.
