Where is the Recycling Bin?

Hi @lriddle46105

Did you have the Recycle Bin turned on before deleting the pictures?

To check if it has been turned on, open the Gallery app and then tap Menu > Settings > Recycle bin.

If it wasn't turned on then do you have a Samsung account or a Google account associated with the tablet and was it sync'd so that the pictures and other data were being backed up to the account?

If so you can retrieve the pictures from the account although there may be a time limit (30 days?) before they're deleted from there as well.

If not, then you may have to use proprietary 3rd part software to try and retrieve them

Here's a link that may help.
