Depending on what version of PSE you have you can perform a search and then use the results to delete what you no longer need.
Find >> By Visual Searches >> Search for Visually Similar Photos
Exactly what I want to do but can not find out how to do it. I do not see amenu item that allows me to search for duplicates?
i am using PSE 6.0
Sorry, it’s not available in PSE6. I think it was introduced in version 9 or 10
Try switching from thumbnail view by clicking the display button (near top right of Organizer) and use the folders or import batch which may help you tidy up.
See that faq by John R Ellis:
That works with PSE6.
Once you have selected a number of files, you can either:
- right click, choose stack and automatically suggest photo stacks
- or the find menu, 'by visual similarity'
