idea for new plugin: auto resize images at upload

I was using scissors: for this but since the image editor was integrated into the core, this plugin doesn't work anymore.

Unfortunately, they didn't integrate the most important feature, namely auto resizing at upload.

There are a couple of plugins for this, but they are old, and have redundant functionality, so why not code a plugin like this?

The reason for my request is, that I still have people upload their 12megapixel images straight from their cameras and then wonder where their upload space went :slight_frown:
