Hi Shelley,
There is currently no way to export images from Method using the import/export function. It is possible thought to create an html report with all of the images, but I haven't tested it.
All of your Method data is backed up daily by Rackspace which is where our servers are located and we have the ability to restore backups if needed but we charge $125/hour for a min of 1 hour.
I hope that helps.
