Graalshop image transfers

[BonzaiXxXSRStudios]

I've been trying to the longest to transfer my images into the graal shop for the longest. Ive transfered them as .png, .gif, and even .mng. I saved them in the ganis folder and the images folder. I made my own folder in the images folder and saved it in there as well, I even took a recent images from the levels/images folder and saved it under another name, same image and dimensions and all, still didnt work.. None of my images never shows up in graal shop. Anyone know what the problem may be?
