can't upload pictures in 2.3.2

For some reason I can no longer upload pictures after upgrading to version 2.3.2.

I have full permissions for tmp & public directories. I don't get any errors, the pictures simply don't upload.

Also, here is the value of my base_url:
$GB_PG["base_url"] = "http://www.bushido-dojo.com/guestbook2.3.2";

Any ideas? Here is the url:

http://www.bushido-dojo.com/guestbook2.3.2/guestbook1.php

Try updating to 2.3.4

Upgrading to 2.3.4 did not fix the problem. Preview doesn't show the pictures either. I have full permissions set on both tmp & public (at least I think I do).

Here's where the new guestbook is running:

Did this only start happening after you did the update to 2.3.2 ?

I can't be exactly sure, but I run 3 guestbooks for 3 different sites and I updated them all when my webhost went to php 5. The version of AGB I was using before was having some other problems with php 5 (not able to store new entries). Is it possible this is a left-over issue with php 5? Are there some php directives I should check?
