Does anyone recognize the plug-ins I have marked with arrows? This is the content of my GIMP plugins folder.

I recognize the photo_mosaic.py plugin. There is a thread here in GimpChat. Cuts an image into specified rows and columns, can add borders, drop shadows, etc. to make a mosaic. PhotoMaster clued us in on this one from GimpStuff...

That's the only one I can verify.

file-ora is pseudo-mypaint open raster format (it gives you the option to save files with the .ora extension)

file-apng is animated png.
There was a howto for that on a Gimp forum but I forgot which one.

That's not one of the ones I have marked. I knew what that one was.

Molten Material..

This plugin will simulate a "molten material" effect for the given shape. To make this plugin work, draw some random blobs onto the canvas and start the "Molten Material" plugin from within Filters->Artistic.

Thanks Rod. I wonder why I installed it.

Thanks, Mahvin. I wonder what I might have used it for. I see the .ora extension in my save as dialog.

I find myself downloading a lot of gimp plug-ins i rarely use or even remember i downloaded...lol

Me too. But they are soo cool - and you never know, you just might need that "one special thing." It's the same reason I have old electronics and miscellaneous mechanical parts stored in my garage...lol
