RealWord Paint, RealWord Photos and RealWord Icon Editor are able to use .8bf image filters created for Adobe® Photoshop® and compatible software. This page lists manufacturers of plug-ins that were found to be at least partially usable from RealWorld software. Since there are far too many plug-ins, each plug-in author shall only be mentioned once. Any registered user is welcome to improve plug-in descriptions or to add entries at the end of the list (in a no-spammy way) - simply click the Edit link in the page footer.

1 paid and 2 free plug-ins for 3D effects. Warning: the plug-ins use a skinning library that interferes with RealWorld menus and displays a error window when the application closes. Also, the 3D shadow effect was not working properly until a special workaround (to compensate for and error in it) was added to RWPaint...

A collection of various filters. Although they have an annoying custom user interface with sliders controls that cannot be dragged, the actual effects are worth trying out.

Some free, but mainly commercial "plug-ins". No actual .8bf effect was installed with the software. The actual Mosaic effect I tested would not be worth a 50MB download (serial number was exchanged for an email address) even if the .8bf file were there and worked.
