Having said that, you can crop images via the viewer pane in another way:
Select part of the image (how you do that depends on your Viewer preferences)
Right-click in the viewer and choose Copy
Activate the main file display and Ctrl-V paste.
You'll then get a new Clipboard Image.bmp of the area you copied. You can convert that to another format if you like using Opus. (The Images toolbar has buttons for converting the selected file(s).)
(If you get Clipboard Image.png or .gif instead you must have Opus configured to paste in those formats rather than BMP. I think BMP is the default.)
Thanks for the tips....my only problem is now trying to get the proper Image Viewer to appear...when I double click an image it opens in Windows Picture and Fax Viewer (on XP)...which has no edit menus etc...it simply shows the picture..and has similar controls down the bottom such as zoom and rotate...but no edit menu etc.
Is this a Vista only feature? Am I missing a setting somewhere?
I've tried right click..open with....but can't see any Opus Image Viewer listed....how do I get Opus to use the Opus Image Viewer?
