The presence or absence of ghostscript shouldn't matter, I have annotated with no problem, and don't have ghost script .

probably the simplest way to put your image in a certain spot on the image is to use gravity, for example, if you want to place the image in the upper right hand corner you would use something along the lines of this:

$image->Annotate(y=>+14,x=>+4, gravity=>'NorthEast', font=>$font, poin
+tsize=>12, fill=>'green',text=>$text);

The options on gravity are, any of the basic directions on the compass (i.e. North, East, NorthEast, etc...) and Center.

Also a simple way to pop the image up on IMDisplay is: $image->Write('win:');
