Well you don't provide a link, so I don't know what entry you're looking at. When I use the data commands, they're just that, a few numbers I want for some reason.
People have written programs which allow you to convert an image into data statements, but it really doesn't serve much more than a novelty purpose for general usage. You increase the time it takes to compile your program, and you bloat your source code, and for no real benefit except a little satisfaction.
However, in the code archives, it may be that people have done this because you cannot upload images and other accompanying files to this site, and so it may be that they've done it so that the source contains everything you need. Again, no doubt with a program they've written. I imagine the program would be included with or nearby the entry in question in that instance though.
