PHP sites wont accept/display images properly?

I run a forum and a PHP based website management software, but images that
have been uploaded to the forum or any website, appear to be partly missing,
ie only half the image is showing (almost like the sender stopped sending
half way through). Is this common and why does it happen? I am running the
following versions of software on my windows xp system.

Apache 2.0.50
PHP 4.3.8
MySQL 3.23.49

Apart from the problem with images, everything else works just fine.

Does anyone have any idea what is going wrong with images?

I am posting in here, because it seems to be related to the websites/forum
that use PHP within Apache. Standard websites that just use Apache etc are
not affected
by the problem and these sites display images properly.

I would appreciate some help with this one, if you have any ideas what needs
adjusting to cure the problems.

Thanks a lot.

The request for images does not differ in this case: The browser
requests /abc.jpg and the server serves the file. PHP shouldn't be
involved in an image request at all.
