Problem Uploading Image

Hi,

I have uploaded pics before no problem, but today I realized after I uploaded that I wanted the pic to have a link.

So I deleted it from the post and uploaded it again, this time giving it a link. But instead of being over and done with after clicking Save Changes, I was taken to another box that contained two thumbnails of the same image, and nothing I clicked on worked. I ended up adding a damn gallery, which I deleted from the post but it’s still present in the upload image box.

I now have 5 identical pics in this stupid gallery, and I can’t delete any of them.

Please tell me how to get rid of this gallery and all its contents!

Thank you
