The scenario: 50 photos to pick for a website/presentation etc.

Steps:
1. create small copies of each photo - I used XnView - say 200 px wide
2. open Xtreme (any version!) and drag the photos from Windows Explorer onto the page.
3. rearrange to your heart's content
4. the name of the bitmap is shown at the bootm in the status line, but you can open the Name gallery (Used Bitmaps section) and click on each photo chosen.
