How are you making the image?

According to StackOverflow, that type of error is raised when you don't create the image correctly, they recommend using:

im = Image.open(pathToImage)
ph = ImageTk.PhotoImage(im)

Then you pass ph

I'm looking for the supported image formats for appJar, so far the only formats I've found besides the standard file extensions is the "PhotoImage" format, so maybe you have to convert it into that format before you display it. Which is kinda silly, but I don't know what else to do.

EDIT: im = Image.open(pathToImage) ph = ImageTk.PhotoImage(im) Did not work.

What I ended up doing was essentially loading the image twice, once with Image.open(filepath) to be able to have a file object to correctly save transparent PNGs with. The next line is PhotoImage(file=filepath) in order to have a file to correctly output to appJar. I now have two dictionaries housing two identical copies of every image I intend to do this with... which is not ideal.

but appJar can't show PIL images, and Tkinter Images can't seem to save in the PNG format correctly.
