Hi Mark,

Not sure if you already discovered this, but you can also simply use an
overplot:

iimage, dist(100)
iimage, dist(256), /overplot

This will add the second image to the window. It will appear on top of the
first, so you would need to do an Edit->Ordering->Send to back to make the
first one reappear.

Now, if you want to *replace* the first image, you could simply do:

iimage, dist(100)
iimage, dist(256), /view_next

The "view_next" keyword places the resulting image into the next available
view in a gridded view layout. Since you only have 1 view, it just replaces
the original image.

If you look up iimage in the IDL Reference Guide, you can read the docs for
the OVERPLOT, VIEW_GRID, VIEW_NEXT, and VIEW_NUMBER keywords.
