[thelist] Feeding image bytes from PHP to client-side JavaScript

[dave gray]

Hi Matt,

I have done something similar to this beffore with Perl and didn't run
into any problems. I can't imagine Javascript puking on that as long as
the script returns a valid image w/ good headers and stuff...

I'd be interested to hear if there are any PHP-specific quirks you run 
into when you get it figured out.

HTH,
