Plug-Ins extends the functionality of the software. PhotoSEAM generally supports two kinds of plug-ins:
Both works similar, but they have different methods of loading. The Adobe Photoshop compatible plug-ins could be found anywhere on the Internet.
The PhotoSEAM/Photo-Brush Extras are "native" plug-ins, specially designed for PhotoSEAM.
