I have a ZenCart shop installed, and I have a working image modification script ready, and it works as I wanted, but we ran into one problem: this script can be used by only one person at a given time. If there are two or more, everything gets mixed, and pictures from one person get uploaded to another person's preview.
So now I need someone to:
1. Modify an existing image modification script so that it can be used by several customers simultaneously. This script modification has to create unique session IDs and tie them with ZenCart 1.3.7 customers, OR make it use ZenCart 1.3.7. session IDs. I'd prefer the latter.
2. Comment this script and make sure I can run several instances of this script with the same or different customers in ZenCart simultaneously.
I have a budget of up to USD50 to do that.
Please bid only if you know how to do it. I can provide a link to a working script.
