Note: These scripts have been written for Gimp 2.x and will not run on Gimp 3.x. Those that are converted to run with Gimp 3.x can be found here.

• Installation instructions are here
• Scripts packaged as ZIP usually have a HTML doc in the ZIP
• Others may have a documentation on the SourceForge project home page
• Unless noted, these scripts should work with Gimp 2.8 and 2.10. However, as of October 2020, they are no longer tested for 2.8 compatibility. If you find incompatibilities, you can ask for help (see "Support" section below).

The ofn-* scripts:

• ofn-average-fill: Fills selection with average color from same

• ofn-coalesce-images: makes XCF files by stacking together all images with the same name in a directory tree.
• ofn-color-select: creates a color selection using the specified color (removes the need to find a pixel with that color to clicko on it).
• ofn-colormap-to-layer: renders the colormap of a color-indexed image as a palette on a new layer.
• ofn-difference-layer: creates a layer with the difference of two layers.
• ofn-dump-layer-hierarchy: dumps the layer hierarchy to the console.
• ofn-enclosing-circle: determines the smallest circle that contains a shape

• ofn-export-layers-cumulative: exports all images created by making layers visible from bottom to top
• ofn-export-sizes: exports image to several sizes
• ofn-extract-objects: extracts non-transparent areas from the active layer and saves them to files
• ofn-file-next: speeds up editing of long series of files by performing "save file, open next in sequence" in one operation

• ofn-layer-aligner: aligns two layers using two pairs of reference points
• ofn-layer-decompose: decompose a layer into layers for each RGB channel
• ofn-layer-modes: mass-change layer modes
• ofn-layer-over-background: makes the active layer the only one visible over the background layer
• ofn-layer-straightener: straightens a layer using a pair of points indicating what should be vertical or horizontal in the image. If you use Gimp from 2.10.4 onwards, this is superseded by the built-in "straighten" function in the Measure tool.
• ofn-layer-tiles: creates tiles/layers/animation frames from a single layer, or joins them into a single layer.
• ofn-layers-to-image-size: applies Layer>Layer to image size to all or all visible layers
• ofn-list-guides: lists current guides in an error dialog (or the error console)
• ofn-luminosity-masks: create a "luminosity mask" selection over the current layer
• ofn-luminosity-tiler: create "op-art"-style pictures
• ofn-manual-stippling: renders a manual-like stippling usin a density map
• ofn-metadata-to-text: create text layers from the image GPS data
• ofn-move-copy-layers: mass-move/copy linked layers
• ofn-name-image: gives a name to an "Untitled" image without saving it to disk
• ofn-outline-layer: adds an outline to layer contents (Gimp2.10 and later)
• ofn-palette-to-gradient: creates a gradient from a palette
• ofn-perspective-stack: creates a perspective view of the image layers
• ofn-pixel-grid: renders a layer as a pixel-art grid
• ofn-points-sequence: adds sequential number labels to an image, using a path
• ofn-preset-guides: lets you define a bunch of preset guides in a file, and then call them using a menu entry or a keyboard shortcut.
• ofn-quick-export: export a file without listing the directory contents
• ofn-random-fill: fills areas with random colors from gradient or palette
• ofn-recolor-text-layers: recolor all text layers
• ofn-remove-grid: removes table borders in scanned text
• ofn-remove-top-layer: removes the top layer
• ofn-reorder-colormap: swap the color map end to end by Hue
• ofn-replace-colormap: replaces the colormap of the current image with colors from a palette
• ofn-replace-font: replace the font in selected text layers
• ofn-retime-layers: mass edits the animation delay specification in layer names
• ofn-rgb-decompose: decompose layer into three layers that represent its RGB components
• ofn-rotate-layer: renders multiple rotated copies of a source layer
• ofn-save-next: saves consecutive versions of a file by automatically determining the sequence number
• ofn-scroll-layer: produce scrolled copies of a layer
• ofn-select-layer-box: creates a rectangle selection over the current layer
• ofn-settings-cleaner: automatically cleans up tools and filters settings that accumulate
• ofn-shred-layer: shred a layer into regularly spaced stripes
• ofn-shrink-grow-selection: grow/shrink the selection by one pixel, mostly meant for a keyboard shortcut.
• ofn-swap-strips: swap two strips in an image
• ofn-symmetries: various symmetries (horizontal, vertical, diagonal and more) on layers
• ofn-tartan: generate tartan patterns
• ofn-tiles: loads/saves an image from/to individual "tiles"
• ofn-trapeze-transform: shrinks an end of a layer without changing distance in the transverse direction like Perspective does
• ofn-ungroup-layers: move layers outside of a group

Removed:

• ofn-reorder-copy-layers: is replaced by identical functionality in ofn-move-copy-layers
• ofn-guides-from-layer: is replaced by identical functionality in ofn-preset-guides
• grid-filler-random-color: is replaced by the much better (and faster) ofn-random-fill

Installation

• If the download is a ZIP file, unzip and extract the .py file. The rest of the ZIP file usually contains some HTML documentation which, while not being necessary for the good execution of the script, is of course recommended reading.
• If the download is a .py file, make sure that it remains so (some browsers may change its extension to .py.txt, if so, rename the downloaded file).
• In Gimp, open Edit>Preferences>Folders>Plug-ins. This lists two directories, one of them being being part of your user files, and one being part of system files.
• Using your file explorer, navigate to the first one, and drop the .py in it.
• Restart Gimp. The menu entry should have been created (read the plug-in documentation to find where the plugin creates its menu entries, it will usually not be in the Filters menu)

Notes for OSX, Linux and other Unixen

• The plugin file must be marked as executable. The plugin extracted from a .zip should have the flag already set (but it would be the first thing to check in case of installation problems)
• The name of the Gimp profile directory starts with a dot, so make sure your explorer shows "hidden" files.
