reading jpeg file

[engrob10]

Hello, I'm a fairly new user to programming and my skills are still very young. I'm interested however in reading data from a .jpg file.

I'd like to know how i can store it, (possibly as an array??)

basically i need to convert it into something i can understand. I mean, if it is given as an array will there be numbers in the array ?? and will those number correspond to a color?? What kind of array is it?

If anyone has examples i'd really appreciate them.

I would post my code, but all it does is allows the user to open a file of their choice then varifies that it opens. (the easy part).

Thanks

libjpeg http://www.ijg.org/ looks promising, I haven't used it though.
