I just wanted to say that yours is the first product that I've tested so far that hasn't failed on handling uploads. This is going to work for a print company, so they are handling nothing but large files and all the other solutions I've tried so far have not been reliable. So far yours has been 100% successful in my tests.
The amount of customization in the program is incredible. I was able to integrate it into my existing page layout relatively simply. I was also able to easily customize the look/feel to match the current site.
I looked all over trying to find a simple cgi script. I found that FileChucker was by far the best. If you have issues with your hosting service's php.ini max upload size then this is the way to go. Looking forward to future enhancements.
