Richard,
Without the code below, I get a good .jpg file and it displays nicely. But,
with the IF statement in, I get a time out error message "Execute time
exceeds 30 seconds..." I think it is because two of the variables are
declared after the IF statement, even though they aren't being used on the
first loop. I'll try to declare them before the FOR loop and see if that
works.
As you might tell from my code, the only software course I ever had, was in
college 20 years ago, and it was in BASIC language (with line numbers!).
However, I find php easy to work with, and have done some amazing things
with it in the last 2 months. With your help and the help of others, I'll
certainly make progress.
Thanks,
Hugh
