“We’re having trouble deleting this. Try again later.” Pictures will not delete from skydrive “other pictures” on my mobile

I dragged two pics into my PC skydrive account in the photos folder and synced them with my Nokia Lumia phone. They synced into a new folder on my phone called "other pictures" . I deleted them on my desktop app but they will not disappear from my phone. When I try to delete them off my phone I get a message "We're having trouble deleting this. Try again later."
Several days later my pictures will not delete manually or automatically from my phone. Any help as this is annoying. I guess I should have dragged them into a sub folder on the Skydrive or something but there is little guidance on this.
