Ah.

Heh. Well, trying to reconstruct what I did with the .png file before
(I had since switched to a different setup using a .gif) didn't work.
Instead, I accidentally seem to have done the right thing; it now
nicely gives me the graffiti image on a background of a brick pattern,
which is what it should be doing.

I don't even remember how it was when it didn't work; but as it now
does what I want it to do, I'd say we can consider this issue
fixed. Thanks!
