'watermark' by Doug Reynolds allows the user to add text as a watermark into an image. The watermark text is done as a lighter overlay of the background of the image. Besides the text itself, the user can choose the font from a pull-down menu, size (in pixels), location (one of the four corners), and opacity (in percent).
After installation the plugin script is availbe under the menu: Script-Fu/MyScripts/Watermark.

PDS/EDR format is the image format used by NASA Planetary Data System and by ESA Planetary Science Archives. PDS images from various space missions are available at http://pds-imaging.jpl.nasa.gov/ and http://www.rssd.esa.int/index.php?project=PSA

With the PDS plug-in you can load images from these missions and others:  read more »

This script tries to fix the tone of a photo taken with wrong exposure. In some landscape photos, it can have a nice effect of enhancing the colors.

The general idea is to produce different copies of the image at different gamma levels, then applying simple tone mapping techniques to produce a vibrant photo.

The script allows the user to control the number of copies by setting the lowest and highest gamma setting then the interval. For example lowest=20, highest=170, interval=10 results to (170-20)/10 = 15 copies with increasing gamma level from 0.2 to 1.7. Play around!  read more »

This is a script that is based on the fire tutorial (http://gug.sunsite.dk/tutorials/tomcat13/). It was built and tested on GIMP 2.4 (so, using the new scheme engine).
It comes with two versions; one that creates an image of flames and another that creates an animation (using layers as frames).

Creates a diffraction pattern using a circular gradient and the foreground and background colours.

Creates an image of rainbow coloured circles to give a plasma-like pattern. Also comes with an animation script that animates the pattern. Frames are saved as layers. Choose min and max speed and circles are randomly increases/decreased in radius according to the set speeds.
TODO - Save frames as XCF files compatible with GAP.  read more »

This is a script that is based on the lightning tutorial (http://gug.sunsite.dk/tutorials/tomcat9/). It was tested on GIMP 2.4 (so, using the new scheme engine).
It comes with two versions; one that creates an image of lightning and another that creates an animation (using layers as frames) of lightning with parameters to modify the turbulence so the lightning bolt appears to dissipate over time.

This plugin does a pretty good job of eliminating shadows and highlights in photographs. It gives you two layers that basically act like adjustment layers, and changing the opacity will alter the effect.

This is a minimal python plugin for GIMP. In contrary to gimpfu-based ones, these do have the functions also available in C plugins (query, init, run, quit) and can (actually, have to) use GTK+ directly to create a user interface.

minimal-really.py

I've attached an minimal-really.py plugin, which does only define what is needed for a plugin (query, and the functions to be used). 99% of all python plug-ins will most likely follow this structure.
