Pretty much. I don't do it myself because uploading large files takes forever with my connection. But as far as I am concerned, anyone can upload the already modified files as they please.So technically you or someone that has a moded version can upload that right? Or is something im not understanding? I just wanna use the gallery. But i understand if you can´t/ do not want to upload it.
That being said, I just updated the gallery mod to include an automatic install script, so you might want to give that a try and see whether it works for you.
