Img backups for all thumbnails?

When image optimsation is enabled, backups of the images are created. However, rather than just backup the original uploaded image, backupds are made of all the thumbnails too.

This is unecessary as all thunbnails can be regenerated from the orignal image, so only the original uploaded image needs to be backed up. If this was the case it would save at least 25% of the uploads diskspace. For resource limited hosting accounts, this is really important.

As example, I have a JPG image that 465Kb with 7 thumbnails. The backups for this one image total 1.5Mb. When it should be 465Kb.

Please can you add this change as a feature request.`
