Problem with textures not existing while also existing

I made a few textures that I was going to use for an animated texture, but I couldn't find any of them when I tried to insert them into the animated texture maker. I then searched the MCreator 1.7.9 folder for the textures, then when I got no results I searched the Pylo folder, and I still got no results, so I searched the hard drive, and still got no results. Even though the textures don't exist, I can still select them as item textures. Help me please?
