drop down menu is going below the screen

I'm writting a blog and adding photos using Blogger in Safari. The drop down menu goes below the bottom of the screen so I can't click cancel, now that I'm finished uploading pictures. I can't quit or I will lose all the work I have done. How can I cancel the drop down box?

I can move the width of the box no problem but can't get under it to lift it up.

I can select a photo and press return, the photo uploads but the drop down box immediately falls back down to below the sceen again. Help..
