PHP/MySQL Image Gallery keeps displaying code or image not showing correctly

[slaterino]

I've posted regarding this link before but have tried everything and am now looking to provide more code and see if anyone can pinpoint the issue. Basically, I have created an image gallery with link:

 

http://www.thedaffodilsociety.com/gallery/

 

When going onto this site and navigating through the gallery, sometimes an image will not show and sometimes all that will appear is the code for the page prefaced by something like this:

 

HTTP/1.1 200 OK
Date: Wed, 30 Jul 2008 19:26:10 GMT
Server: Apache/2
X-Powered-By: PHP/4.4.8
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
Keep-Alive: timeout=15, max=92
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html

1088

 

I've restarted the Apache server which has not helped. I have noticed that some of my album images are saved with an extra full stop. For instance, they end in ..jpg. Can anyone spot why this is happening?

 

I've included all the code for my config.php and functions.php which I think are where the problem is most likely to be. If someone can help point in the right direction with this that would be amazing!!!!

 

Thanks so much,

Russ
