I made a post here a while ago about this topic, but I've finally been able to put some time into it again, and I've made some progress. I'm up against another wall, though.
I have a php file that creates the thumbnail, and I call it in the <img> tag. I am calling the script multiple times on the page. Whether it shows the image correctly or shows a broken link seems to be completely random, even though the src url always shows the thumbnail correctly.
The code that I use to call the script is as follows:
The script that actually generates the thumbnail is as follows:
I have seen pages where this strategy works consistantly. I just haven't been able to find where my script breaks down. Like I say, when I access the script directly with the url, it works every time.
