Euhm, I assume it's deleted by another request later on? Can't hardly be=

And the rest of the reply is about an image. Now I'm confused :). What =

when, and why.

I'd reexamine some things in you code carefully:
1. Is an image actually creted, and where? Change the filename to =
something unique you haven't used before (uniqid()?), and check for it =
(remove the unlink() temporarily).
2. Is the HTML src attribute actually pointing to that image, or perhaps=

an image in another directory with the same name?
3. Is an image actually deleted? (reintroduce the unlink(), check wether=
=
the file actually disappears.
