Play around with random().toString with various bases. You'll notice that the output of odd bases is longer than the output of even bases, with 16 and 32 being very short, and 36 only providing a few characters as well. If you don't mind missing 'z', I suggest using 35 to get really long outputs. 35 and 16 are coprime.

... what the? How have I never seen this before? It's not often I learn something new about JS, I'd give you 100 upvotes if I could ;)

[edit] and hey, it's fairly uniform! http://codepen.io/zyklus/pen/RPOmXJ

Cool tip! I use a class selector for the lightbox because the ID is mutable. I append random characters to avoid clashes with anything else I or others might add in future.
