I find myself positioning guides the same on many pictures. This got a bit tiresome, and everything tiresome is a target for a script. So it started as a small personal script and then I made it a bit more fit for human consumption. In its present state, you create a small definition file like this:

And you end up with:

Plugin is in ofn-preset-guides.zip at the usual place. I'm inaugurating a new naming scheme and packaging, I hope you like it.

Enjoy.

Works fine here: Gimp 2.8.14 & Bodhi linux (netbook)

Only one comment, I use a folder ~/gimp-2.8/plugins-test (for the named obvious)
ofn-presets-guides.ini does need to be in the regular ~/gimp-2.8/plug-ins for ofn-preset-guides.py to read it.

Unzips with permissions set, still have to wade through the html

Thanks for checking. Fixed it, now both config file and log should be in the same directory as the plugin file. This may cause problems if the script is installed system-wide, though.

Thanks ofnuts, nice and handy.

I wish I could use it. I'm confused on how to install it and I'm not that good at creating files for things to work. I'm using Windows 7. I'm using gimp 2.8.10

MIght have a closer look at this when I get home.

Extract files to user plug-ins folder.
Image menu => Guides => Presets
User presets: ofn-preset-guides.ini
Instructions: ofn-preset-guides.html and README

If you need help customizing guide layouts ask away.

I figured it out. I got it to work.

Check 'ofn-preset-guides.py' properties to make sure it's executable.
In Gimp user folder you normally have only one plug-ins folder. Is there anything in the sub (additional), plug-ins folder?
Which folders are listed in Gimp Preferences => Folders => Plug-ins Folders?

The nice thing about the ZIP packaging is that it keeps the executable bit, so the .py should be executable without user action.
