Deleting pics

Hello,
I would like to delete some pictures i posted, and i remember there was a way one could go to the whole list of pics one had uploaded, but right now i can´t find a way
SO my question is exactly how can i access to the whole list of pics i ve posted?

And also, do i hqave to delete them one by one? isnt there a way to batch-delete them all at once by marking and deleting a few at once?

Thank you, and sorry for the double posting
