Image Dimensions Part 2

Asked by pertrai1 in PHP and Databases, PHP Scripting Language

Tags: php & databases

Hi, ali helped me out on some of this so far. We have come to determine that I need my memory_limit increased in php.ini. Only problem is that I do not have access to this and my web host is not playing nice. So here is my question: Would this work:

ini_set("memory_limit","24M");

I saw it somewhere and I tried it and it did not. But, I do not know if I was using it correctly. If this would help with my php.ini problem, how would I implement this into my script and where?

Thanks much.
