In first place I create a skin including all picture files provided in the skinning pack.

Then from the picture filenames I try to put them in directories corresponding to the various game panels.

And at this point, I use some tricks to find out which picture file is my definitely my target.

If I'm uncertain I found the right picture, I use xnview to push its red balance at max, then push the "save" button, then I force the refresh of the skin ingame, by wearing another skin, then wear back the previous, and then I check if the element I expect has become reddish, and then I can cancel the change in xnview.

If I have no idea which is my picture file target I eliminate suspects by lots :

I send half of my present skin folders into the trash then I refresh the skin. If my target file is in the trash, it will appear greyed at the screen ingame.
If yes I restore all the files sent to the trash and delete only half of the previous deleted folders in order to get a sharper elimination test.
And I reduce the targeting test after test.
