Deleting uploaded submission images to free JotForm available space

I use a form to upload images, but then I download them locally.  How do I delete them so they dont use up my available JotForm space?

This is possible to delete form entries with their associated files from Submissions page. Please take a look at the following support thread.

It seems that you have already cleared the upload space and your account is fine. If you need any further assistance, please let us know.
