GIMP 2.8 Python Plug-in.
This plugin allows you to duplicate layer, layer with mask, or layer group from one image to another.

Installation:
1. Extract "duplicate-to-another-image.py" from zip archive to the ".../.gimp-2.x/plug-ins" directory.
2. If you're on a UNIX system, make sure "duplicate-to-another-image.py" is executable.
3. Once you have saved the file in your plug-ins folder, if you are already running GIMP, close and reopen it.
4. If you have done this correctly, the scripts will appear in the menu under: "<Image>/Layer/Duplicate to another Image..." and "<Layers>/Duplicate to another Image...".

Looks interesting, could be very helpful.

Can't you can drag and drop layers betwen images already?

sure but do the same with layer mask is not so easy

Hi all,

I have gimp2.8.2 on ubuntu 12.10, it does not work for me!!!

I have 2.6.8 on Ubuntu 10.04 and it works perfectly (drag from Layers list#1 to canvas#2). File a bug report?

No need for that. It was an accidental feature/bug in 2.6 disabled in 2.8. Will be reintroduced in 2.10.

If the layer has a layer mask it comes with it...
