I have pictures in my iPhone 4 in a album that says its from 'My Computer'?

I was wondering how do I transfer these pictures from the phone to my computer?

Also, how do I delete them from the phone itself? There's no option for me to delete the pictures.

I have a photo album on my iphone that was added by my computer a while back to sync from my hard drive to the iphone. I then started using iCloud to back up instead of my computer or hard drive. Now I have no option to delete the album or the pictures in it either from the computer, iTunes or the iphone. Any ideas on how to get rid of that album? It's taking up too much room and I need the space for new pictures.

Try to back via icloud or itunes in pc and then select the option which does not allow sync of any image
