HOW TO READ AN IMAGE DATA

I would like to know how i can read the data of an image, a jpeg file for example.
So i imagine it would look like a big list of numbers, i've tried with notepad but the data is corrupted.
Also i don't want to read the metadata but the whole written data of an image, jpeg or any other image format.

I would decide what programming language you want to manipuplate the data in and look into a book about that programming language. I know it can be done in most if not all languages (Java, C,Visual Basic). I do not know what you intend to do with the numbers you want o see, perhaps you could explain why you want to see them.

The image data is in binary. You can't read it in a text editor like Notepad. You'll need a hex editor. Or through a data dump software.

I wrote two Java freeware before, called BinDump and HexDump. These free software dumps the data in binary and hexidecimal, respectively, on the command-line. You can get a copy at Cynosure.X International: Products.
