So I downloaded it and created a plugin from it. Since then – Sunday – it’s proven extremely popular.
A lot of people seem to be having some issues with it and I think the bulk of them come down to two things:
First you need to have the GD Graphics Library built into your PHP installation. This is probably the main contributor to the problem. The second issue is probably not having your cache folder for the plugin be writable. I’ll be glad to help anyone – within reason – get these issues resolved.
I am pretty much constantly trying to work on this plugin to get it up to version 1.0.0 – it currently sits at 0.5.5 and as such is functional but incomplete.
