I'm at a part where I need to be able to find out the currently active image (the image that is selected in gimp). I have tried:
activeImage = gimp.image_list()[0]

When you call the plugin's main function, you will automatically have access to the current image and drawable.

So something like this:

def my_plugin_function (image, drawable): print image

Will output the image object if gimp was started from a terminal. This is a bare-bones plugin that adds guides to the current image: http://registry.gimp.org/files/rule_of_thirds_guides.py

Thanks for the reply.  I do realize that the current image and drawable is passed to the plugin when first opened.  Perhaps I should explain further. I'm trying to build more of an extension that is opened just once, and updates as you move from image to image. (Its a time tracking window which stays open along side gimp).  I wanted to make it so that a new instance of the plugin doesn't have to run for each image - just open it once, and it "knows" which image is currently active so that it can populate my sqlite database.

Is there a way to do this at in in gimp?

I'm not sure (reposting to list - be sure to 'reply-all' vs just 'reply').

No, there is not - at least no clean ways that I can think of. There is nothing on the GIMP's API that marks an image as the currently active image.(The "unclean way" I can think of would mean to use GTK+ instrumentation for GUI debugging to be able to introspect active
windows, and infere the active image from its title)

Another "unclean", but tidier, way would be to create a very simple script, with no parameters but "image and drawable" that would just signal your main plug-in when called - and you could bind it to a shortcut key and press it everytime you switch the active image.

To notify your mainplug-in you could use some file-system signaling mechanism, xmlrpc, or some gtk+ mechanism..

I'd use this second approach.
