Deleted photos using the undo button by accident

[salvage]

I plugged my samsung into my computer and copied and pasted my camera folder into my pictures, in a new album.
Selected and deleted the photos.
Went through to check other albums on my phone I'd created and accidentally moved one. Hit undo on the screen and bam a dialogue box wizzed along and said deleted. 1000 photos, they are no longer on my phone, in the created album (now just called new album) or in the recycle bin.
Yes they are baby photos. Absolutely gutted and just cant figure out how to get them back.
The photo app on my computer doesn't seem to have a recently deleted file which is all i can come up with on google.
Can anyone help?
Thanks.
