I've installed an Image Resizer
This means that when you go to post a 3MB image that's like 2000 pixels in width, you won't have to scroll like an idiot. Instead, now it just automatically creates an 800 pixel wide thumbnail that fits nicely in the window. If you click on the image you can still access the ridiculous size of the image if your passion is spotting cracks in fairings, hey Ned
Enjoy
