Note that selecting "Change Src 1" (or 2) button followed by the "Current Target" button it is easy to merge more than two images or text in any combination.

For each and every target pixel at a given location, merge will take the pixel at the same location from the two images and merge them according to one of these selectable options:
You can adjust the weighting in percent between the two sources for the merging process. The default value of 50% denotes equal biasing between the two source images.
There are other options available where the 'else' statement is replaced with the background color.
Originating from two images these samples are in turn: average, darkest, brightest, subtract21 and subtract12. They have not been touched up with local blending.
There are three options available for batch merging:
In each case source 2 image files are always loaded from a directory to be merged in turn with the contents of source 1 however that is generated from one of the three options.
Relative positioning, scaling, merge parameters and brightness and contrast are all set up before running this command. If you don't like the result then simply setup the parameters again and retry. None of the originals are lost.
If the watermark image (always source 1) is text then a good tip is to set the merge method to 'Brightest' if white text or 'Darkest' if black text.
The merge (version 2.9 only) plugin to enable perspective transform is available for download. here
Version 3.0 does not need the plugin for perspective transform to work.
With MERGE you can smooth-blend part of a source image to the destination.
Here are two source images: the cat for source 1 and the dog for source 2 (it becomes source 2 as it is loaded after the cat.)
There are several choices of effect: Blur, edge, emboss sharpen, soften
This example was generated by selecting 'emboss' followed by smooth blending of one source image against another.
These are another selection of surreal effects.
