Photo editing

hi all, well im off to a bit of a hash of a start! (considering my first post here is a plea for help!) in my haste to get started i have come across a little problem! It's a case of 'should of read the instructions first! DOH! ok well to the point at last..... i planned to upload 10 pictures, it stared fine, i chose the pictures clicked submit got to the bit where you add comments and choose what gallery you want them in. Again that was ok untill i clicked upload, at which point i was informed that the page would not load, so i clicked refresh same again so i gave up, to find that some of the photos had indeed been uploaded multiple times and some not at all. Now when i try to edit them i cannot delete the copies as i dont have permission. so can it be done or could a kind modderator please delete them please! thankyou.
