Coppermine won’t arrange my pictures

I posted this to Coppermine forum but they weren’t any help at all. I find that I cannot, for the life of me, arrange my photos the way I want them to be seen.

Here’s an example: I have pictures of smoke stacks as they were being blown to smithereens. Obviously I want to start with the picture where they are standing, then down comes the first one, the second one, etc. I even named them 001, 002, 003 etc. Still, they show up with the last picture first and, where they are still standing, last. The following is the link to what I’m talking about.

Any suggestions?
