I assume you are referring to the server load issue. I am kind of worried about that too. Although we where just testing the mod (only admins and moderators could use the features) I decided to disable the plugin for now. But of course I am looking fw to enable it again.
DF031 I have ran into some personal issues that is going to delay the release of an update for a bit. So I don't want you to be sitting waiting, I have changed a file to make it work. Redownload the zip, and upload dbtech/vbsuper_pm_pro/hooks/pmattach/editor_toolbar_start.php
That should allow you to upload images from your computer using the Insert Image button now.
