No. Photos from your media server do not get discarded from the frame automatically when it receives new photos, so there is no need to lock them. If your frame is displaying photos that you want to remove, you may be able to fix this with a filter option or by creating a directory to share on your media server with only the files you want to display.

If you wish to order prints of your photos, you can upload them to an album in your account at ceiva.com and order from there. Click here for more details.
