how to delete a photo
If you mean you'd like to delete a photo on our site: http://www.funadvice.com/photo/view/13293
There should be a link in red at the top of the page there "delete a photo" if you want to delete it.
If you're talking about some other site...you'll have to elaborate more.
You could go to your profile and then where it shows your primmary photo, next to where it says primmary, you will see ''delete''. And click on that and it will delete a that photo for you.
could you elaborate more on the question?
