Online Photo / Image Editors (+ Edit)
Back in June, 2007, we posted about Online Photography Tools and Resources. The Mashable blog recently featured 20 Great Online Image Editors (some free, some subscription-based) that are worth a try. The Daily Gyan blog also recently posted 10 Online Photo Editors That You Definitely Need to Bookmark.
Online image editing has some advantages. No software installation is required, and, like other online applications, they are platform-independent. These attributes make using borrowed or non-Windows computers a snap when editing photos or images.
Edit 02/25/2009:
CNET recently posted a feature comparison of a group of 15 online photo editors–big and small, to see what each one is capable of. All but two are free.
