It’s a newby question but how do I delete the uv images I loaded from my game?
Sure I can deselect them from the object but the list of pictures is full of once I don’t use…]
Thanks. 
go on your UV image editor and whit a loaded image just uncheck the gift icon, that way that image will not be in your file, then remove the file from its folder, then save your project. Make shure that all your materials with that texture dont have the texture anymore and go to file external data and make all paths abosolut and relative, i think that ll work
Any images that aren’t used by anything will get dropped after you save and reopen the file a few times. If even one link exists they’ll stay, though, so just make sure they’re not.
