Help with my image

Help! I have attached the code with which I am having difficulty (I have also attached the php configuration of my host provider). What is happening is that I can call up a jpeg file from ./maps and see that it makes it through to the next page, and I can then call the next jpeg file in the sequence, from the same sub-directory, and I get a broken link (error 500 page). The jpeg's I'm working with are 30 to 100 KB , not overly large, and they have names like grid_a.jpg, grid_b.jpg .... grid_l.jpg. The jpeg files view fine in PhotoShop5.5 and are whole files with proper termination. It is the inconsistancy of the problem that is driving me nutz. I work on it for a while and get some images to pass, and then for no reason I can fathom, they stop going through. At one time, I thought it could be a path problem so I did a copy("./maps/$map","$map") to get the image file in the same directory as the image program. The jpegs were delivered, but I still had problems with getting images out. I also thought it could be a database problem, so I stripped all the records from the table. Still no change, some jpegs got through some delivered the error 500 page. If anyone is familiar with using the gd files I can certainly use your help. I'm dead in the water on this.
