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.
Thanks,
Hugh

When the only tool you have is a hammer, everything looks like a nail.
