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.
