That is correct operation. The img tag is a directive to the browser to
load the image. However, right after creating the image, you unlink the
file. So when the browser requests the file, it no longer exists.

But don't delete a file before it's being used.


Probably the best would be to have the img point to a PHP file which
serves the image then deletes it.
