What means "read successfully"? Is it a valid image? Is the response
from the server valid?

Firefox offers to option to clear the cache - no need to shut it down or
to rename the file.

Either Firefox once got an invalid image and cached the response or the
server does not respond the way you think. Maybe a BOM in the PHP file?
This may not be visible in your editor, but it can cause all sort of
