How do I open a photo from iPhoto into Gimp?

I'm sure this is easy once I figure it out, but how do I open a jpeg in iPhoto into Gimp?
thanks!

 

Go File>Open then do the following:
- Go to 'Pictures' - iPhoto Library - Data

Then go through the sub-folders until you find you photo.

 

Or just drop it on the desktop and then drop it on the gimp icon in your dock....

 

doesn't a drag and drop from the iPhoto browser directly onto the Gimp.app icon work?

 

This worked for me. (MacBook - Late2007 version, w/Leopard and iPhoto'08)

1. In iPhoto’s menu bar select/click [iPhoto > Preferences...].
2. In the Preferences window the very first icon at the top is – [General] click it.
3. Click on the selector to the right of [Edit Photo:].
4. Select [In application] a file selector drops down.
5. Locate and select GIMP (if it is in your Applications folder just click on it,
    otherwise you will have to find the folder that GIMP is in.)
6. Once GIMP is selected click [Open]. - Close the Preferences window.

Now when you click on the [Edit] icon (at the bottom of the iPhoto window),
the picture(s) that you have highlighted will open in GIMP.

I think this was what you wanted.
In that case: I hope this works for you.
