This plugin adds cropping, resizing, and rotating functionality to WordPress’ image upload and management dialogs. Scissors also allows automatic resizing of images when they are uploaded and supports automatic and manual watermarking of images. Additionally, images that are resized in the post editor are automatically resampled to the requested size using bilinear filtering when a post is saved, which improves the perceived image quality while reducing the amount of data transferred at the same time.
Custom image size supported!
Check settings of this plugin after activation. Watermarking function must be set before using!
Please note that WordPress versions 3.4.2 and older are not supported!
This plugin builds on the plugin Scissors Continued v2.1.
