Help on a new technique

I have done following things.
1. I have took a file around 50mb.
2. I split it to 500kb files.
3. Encrypted it with AES with different key for each different chunk.
4. I read the each byte of the each chunk and map it to RGB values. (3 bytes for one pixel) and generated a image.
5. The I have created a file called map file with keys. The person with the map file only can decrypt the chunks and combine them in proper order.

I want to add more feature and find out how to make my technique useful

Please give me your feed backs.
