The pictures that I took with my camera I can delete those. However I decided to play around with synching photos to see how it works. I accidentally synched the same photos twice. I now want to delete them and there is no trash can anywhere! There is no option to delete! What's up with that?
In iTunes under Device, go to your iphone. Select the Photos section, then un-click Sync Photos From.... That will remove the extra albums. Or go to the folders on your computer that iTunes is set to sync with and delete the photos from there.
