How can I undo the deleted field in the form to restore its submissions?

I accidentaly pressed delete and i've lost all the images from my jotform. Can I undo this action? Please help

If you mean you have deleted a field, then try recovering the submissions by reverting to the earlier version of the form. Here's how you can do that: https://www.jotform.com/help/294-How-to-View-Form-Revision-History. 

Thanks Welvin! I actually found the answer after I had posted the question but couldn't work out how to delete it. Thank you for your help
