My favorite plug-in of all time is Flexible Upload. I use images a lot on my weblog and it sure made life easier than the image handling in WordPress.
Unfortunately, Flexible Upload is not working with WP 2.5rc1. I have left a comment on the author's page asking if he would be upgrading the plug-in, but so far no reply.
Is anyone else using this plug-in with 2.5? Is there a simple hack that can be applied (a programmer I am not) to make it work with the new version of WordPress? Any help at all would surely be appreciated.
