Cannot close the Upload Option, missing X tab??

Hi have got the mega profile mod and was wondering how to solve this issue. I have change the finestra.png on the 'upload photo' part... /modules/ibdw/megaprofile/templates/uni/img/finestra.png  same place as crop and other many option at the top right of default profile pic. Anyway because I change this image to a more suitable one for the template due to the text not displaying, I seem to have lost the top right close button X, it still closes but it's invisible aarrggh any ideas how to remedy this please. My new png image is attached for reference.

Many Thanks Dane
