I have a couple of ideas to give a functionality 'sort of' like you asked for; they may require writing some javascript to manipulate another window/frame.

1.You could put a thumbnail version of the document in the metadata of your document - thus allowing you to display more while browsing;  (javascript or css could be used to keep it hidden untill selected)

2. (for images only)embedding something like [<br><img src="/gsdl/collect/gsarch/index/assoc/[archivedir]/0/0.jpg">] in my format statements lets me include the first page of a document in my search results/browse - a bit unweildly by itself but as with the thumbnails is not to hard to add a bit of javascript (or CSS) to make it neater.  (Could be extended to the first few pages)

3. (for text) Embed a copy of a portion of the document in the metadata - I don't think greenstone/mg cares what you put in metadata fields.- then display it with format statements and javascript.
