EDIT: Sorry, I didn't see you have pictures on the drive. Basically, you are going to have to reformat the drive and start all over. Trying to put the trash back to the drive won't work, the backup database is totally hammered and ruined. So copy off the pictures that are there to somewhere else and erase the drive by using Disk Utility to erase and reformat it. After you have erased the drive with Drive Utility, then to make Trash look clean, you will have to resort to using Terminal.
CAUTION: What I am about to suggest is VERY, VERY powerful, and if you do it wrong, you can erase your entire hard drive, so read
everything first and be very careful.
Double check everything. This set of steps cannot be undone and you don't have a working backup, so this is a high-wire act with no net.
Open Terminal.
Type in this, exactly (Do not hit return at the end of the line yet):
Check that you have entered it properly, and then hit Return. The command will execute immediately, with no further warnings. That should empty the trash. Basically the "rm" command is remove, the -r says to make it recursive (that is, burrow down to all folders and all files, and the "f" says to Force the removal. The "~/.Trash/*" points to YOUR trashcan in YOUR folder and the "*" says "everything." So the command is to remove (including all files and all folders) all files in MY TRASH. That's what you want, so that should do.
If that doesn't work, you can try this:
After double checking that you have entered it correct, hit Return and you will be prompted for a password. Enter your Admin password carefully. It will NOT show on the Terminal. Hit Return once you have the password typed in and the command will execute immediately with no further warning. The addition of "sudo" make you a super user for a while, giving the command even more power.
Once the trash is empty, you can use the newly formatted drive and do a clean start on Time Machine, or for a CCC or SD clone backup.
