Image Manager addon

[boudewijn]

Both Combined copy/resize and Autofix seem to be making the small image (600px wide and @ 150kb) small BEFORE creating the medium and large images, which is resulting in all the images being pixilated.

So am able to create "large" image, but then the option to resize the small one doesn't seem to be offered.

If this happens, something else is wrong. The order is:
1. copy to large, resize/watermark large
2. copy to medium, resize/watermark medium
3. resize/watermark small

Watermarking only takes place if a watermark image is in place, see the image_manager.txt file.
