Try this boring script (big view of WTC, NY..) REBOL [ Title: "Remake of view-image.r ;-)" Date: 15-November-2001 Author: "Arnaud Danassiť <[bigdan--migazone--com]> - Badger Dev" File: %wtc.r Purpose: {Wonderful 14 Mo JPG of WTC, upload on aminet by [pairio--cs--joensuu--fi]} Category: [view VID 1] ] view layout [image http://de.aminet.net/aminet/aminet/pix/misc/wtc-photo.jpg] Not enought memory (9372x9372 pixels... arghhhh)? try instead (for example) http://rebolfrance.multimania.com/propagande/login89.jpg More seriously, i am working on a reduction of this jpg in more decent size with a system like map in html to display portion of this jpg (no scrolling view yet ;-( Any ideas welcome, thanks.

Hi Arnaud, I beleive Jeff posted a program to scroll around a large face, it automatically added scroll bars if the image was too big to fit in the window(?). It did however not show the extreme edges of the image though. I posted an update to the a image scroller started by Bo This one does show the edges of the image as it increaces the face size to add the scroll bars.
