The Crop & Download feature become extra useful when you create present that are coupled with a processing profile.

In the config on the showcase site we have created a processing profile that stamps pictures with a 96dpi resolution.
By then creating a Crop and Download preset that uses this processing profile, you can crop a picture and get a reasonably sized downloaded asset that's suitable for screen viewing. This is how it's done:

• A processing profile stamps the image with a 96ppi resolution. (The processing profile is added to a processing profile set, which in turn is enabled on the archive.
• A Crop & Download preset is made to use this processing profile and also set the max width of the output file.

What other preset sizes /labels would be practical here?
