Hi everybody :
  I'm still learning my way around GIMP. When PASTEing a photo 
into an "open" photo (setting the inset photo as a layert),  is there a 
way to "unerase" the layered photo when I make a mistake. In other words,
to "fine tune" ERASEing  the inset image to match the outline of the 
base image ?

document.oncontextmenu = null; document.body.onpaste = null; document.body.onselectstart = null; document.onselectstart = null; document.ondragstart = null; document.body.oncut = null; document.onmousedown = null; document.body.oncontextmenu = null; document.body.oncopy = null; document.body.ondragstart = null; document.body.onmousedown = null;

What I do is paste the second image into the first (base) image as a layer and then (with the second image layer selected) use the eraser tool to get rid of what I don't want in the second image.

Use a layer mask, it is non-destructive see:

Quick example: looks like this:

Look into making a selection then create the mask from the selection. One of the options in Layer -> Mask -> Add Layer Mask.

Another way is to feather the image/layer. You don't want to cut your image too close if you have a large feather - This will show as gradually going into your background picture then.
