WordPress has a very nice and simple editor that uses TinyMCE. As of WP 2.8, there is a load of new functionality in the image uploading and management department, with the new Gallery functionality. I like the way WordPress handles all of the image files attached to a post… it lends itself to slideshows, etc. But recently I had a question about rotating images within the editor, and I went searching for a plugin to do it… and found Scissors. This plugin adds cropping, resizing, and rotating functionality to WordPress’ image upload and management dialogs.
I just loaded and activated Scissors, so I’m going to try it out to see how it works…

this image is rotated

this image is resized

this image is cropped
Well, it looks like it works just fine! Another plugin that’s just become a necessity for client sites!
The functionality described above (crop, rotate, resize images) is now part of the WordPress Core, as of version 2.9… no need for the Scissors plugin now (about the only thing it adds is watermarked images).
