This plug-in will create guides every X pixels apart for the entire image size. It can handle both vertical and horizontal guides.
I wrote this for easier management of multiple textures and sprites in a single image file for graphical programming.
Copy the file in to your Gimp scripts directory, usually '~/.gimp-2.x/scripts'. Refresh the scripts from Gimp menu 'Filters'->'Script-Fu'->'Refresh Scripts'. This is unnecessary if Gimp is being re-started. Once this is done the script can be accessed from 'Image'->'Guides'->'New Guides Every X Pixels'.
Creates a separate thumbnail of the selected image file(s), pre-pends 'th_' (color image) and 'thgs_' (grayscale image) to the filename. WebThumb takes maxPixels as the maximum size of the largest aspect of the image, and then sizes the opposite aspect to maintain the original ratio.
FX-Foundry project is constantly updating custom scripts for each major Gimp release.
Last pack contain more then 100 scripts updated for gimp 2.6
In case you do not need such huge pack you may also search (for category, name, author's name etc) and download single scripts.
Note that many scripts included are not listed in this registry, before ask in this or other gimp forum help to update some old script you may better check on FX-Foundry ,good chances was already updated
This is a very simple script that adds the rule of thirds guides to the current image.
I used to add guide by guide by percent, then crop, remove the guides and add them again one by one. After many times I did it like that, I decided to create a script to do it faster, for which I had to self train on how to do it using script-fu, to avoid poor portability.
I created the script with my Fedora 8 Linux distribution for GIMP 2.4, but it also works for 2.6.
This script works for any platform that GIMP works with.
It is a python plugin (so you need to have python installed) that can dynamically manage all the resources that gimp can use. (It is basically an extension of the brush manager plugin). He has given me permission to post it here :)
The G'MIC plug-in for GIMP proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc.. It is a quite large plug-in, integrating a lot of different effects.
Windows 32 binary of the last version of this plugin written by "wavelet" Marcor ;)
(2009/12/26) New compilation of same sources. French localization added. Locale dir fixed this way:
LOCALEDIR = /PROGRA~1/GIMP-2.0/share/locale
Which means (any drive)/Program Files (or Programmi, and so on...)/GIMP-2.0/share/locale for your language files.
We already did the same for Liquid Rescale. Another compilation would be needed for a portable version of Gimp, else the plugin would work in English.
