Hi there... greetings and respect for all the work done on a fantastic project

This is the second or third time I have used coppermine (usually no problems) I am no expert but not a coding novice either. However, I have a problem I just can't seem to fix and have burned out looking over the board - but found no similar problems.
I am confident that the permissions (chmod) are correct (but prepared to conceed that one more check will do no harm). All seems in order with the php and GD intallation except for the one feature that the server has disabled -
proc_open, any advice welcome on that one. Details from the debug below...

server system ......... FreeBSD 4.8-STABLE #0: Mon Apr i386
I use both Firefox 1.3 and MS explorer (firefox mainly)
The actual installation of Coppermine was a dream, inc the mysql etc. The gallery is running well and correctly except for the fact that the thumbs and the intermediate picture do not display

The system is generating the thumbs and mid sized picture and placing them in the correct folder. I have verified this by accessing the folders on my server via my FTP client (flashFXP) and I can view the results (all three images, which are perfect) via the FTP and Fireworks.
The main (full sized picture) displays with no problems at all. This can be effected by clicking the (broken link) image displayed where the thumb etc. should be. So I am guessing that the problem is not a permissions issue!
I have checked the path (via right click - properties) from the place holder for the thumbs and all seems to be correct - the path should lead to an image which is most certainly present and correct in the folder.
So you see I am rather stumped! I have even tried removing all traces of Coppermine from the server and reinstalling it (including removing the dbase and creating a new one.
I stress again that everything else is working perfectly, the thumbs are being generated correctly and the links displayed in the albums ... it is just that the thumbs and mid-size images are not displaying.
Any ideas - suggestions - help would be appreciated and thanks again for a great picture gallery - I am sure that the problem will turn out to be something small which I have overlooked!
