Is great at what it says it does. My only gripe is the one meg limit. I understand the need for a pro version, but given that most photos uploaded are in the 2-3 meg range, its close to making the plug in irrelevent for me and my clients.
Personally I would rather that the plug in would handle bigger files and give up the convenience of bulk smushing to the pro version. Its better to show the power of the the plugin in the free version and use the pro version to make life easier no?
