Hi Juan - I don't think it's assigning the string that's slow. It's calling
sendAndLoad that is slow, because I think when you make the call the data is
urlencoded or something. I've already found that, and am not calling it. I
was simply outputting the before and after string lengths to see

Yes, you're probably right. I thought maybe the string was encoded as soon
as it assigned, but it makes more sense that the

Right, I mentioned that. :) I kept it simple to be able to reconstruct the
image from it more easily in PHP. Gotta try the base64 thing next.

Actually, from my tests (on the component I made, which was AS 3.0), the
bottle neck was not encoding to base 64 per se (as I assumed at first), but
assigning the resulting string to the LoadVars object (o URLRequest in my
case...). If I commented out that specific line, it worked way faster; when
Interesting stuff. I assume you're creating the jpeg on the server since you
seem to be passing the raw bitmap data (compressing the pixel data with your
algorythm).
Perhaps another approach worth trying is creating the jpef directly on the
Flash app. Have you tried it?
I've done that with
