#1574 How to add new files?
ok so basically idk anything about this program im just trying to add a new png file but all i can do is replace files that are already there. I tried using the import buttons but i couldnt get it to work. How do i import a png file without replacing an already exsisting file?
You can right click images section and select Add tag->DefineBitsLosslessTag. Then select new tag in the tree and hit replace button and select apropriate image from disk.
