No, that acts as the maximum size that they can upload.

To keep smaller images, set the resolution for each file type lower (maybe 600x600), and tell it not to keep the original image. You can't tell it to reduce images to a certain filesize, but you can tell it to reduce it to a certain resolution to keep it close to the max. filesize you are looking for.

This way you can set the maxium upload size to a higher byte size (say the 2meg default), because that original image won't be kept anyway. It'll just be used to create the lower resolution version, then removed. This will keep users from having to rescale their images on their own to get it down to your 90k limit, for example.
