I would think if you were going to place something fairly abstract as a picture, something like computer coding. Then why not have it either be instantly meaningful to some coder as something that jumps out and grabs them, or else some code written in the shape of Yoda, a Squirrel or appears to depict a Cat or something noteworthy.
If it just looks like 'code' how many people are just going to get into it, I think pictures need to bait the story and add impact; and of course images should not be used without permissions...
good luck out there,
c u on the BC ;)
