It is not clear what you mean by seeing multiple images. Could you clarify? What are the steps you took?

Also do be careful when encrypting images with AES. AES can be used in several modes of operation. And using the plain old AES mode, called Electronic Code Book (ECB) mode, to encrypt an image, is a bad idea. Use one of the more advanced modes of operation. AES is a block cipher. And simply using ECB mode to encrypt an image will show off the information in the cipher text when viewed with an image viewer.

Is that what you meant? You are seeing the image even after encryption?
