WordPress › Enable Image Scaling on Upload

This enables you to set maximum height and width dimensions for images uploaded through WordPress.

Have problems with large images clogging up your uploads directory and taking up more space than necessary? Now you set a set of dimensions that all images will be scaled down to when uploaded through WordPress.

Complete 1.0 Rewrite!

Supports the new Media Manager workflow introduced in 3.5
3.5 Only: Set custom height and width dimensions instead of resizing to the "large size" dimensions
Fully backward-compatible to WordPress 3.3

Now translated to Dutch! (thanks: Theo Houtman)
