I deleted some pictures that I dont want my mom to see(Im 26 but shes nosey) when I deleted them it said they?

went to the recycle bin, can she still easily retrive them? I want them gone all togther, not only do I not want my mom to see them but noone else either, one of those wild times I wish would just go away so how do I make sure these never reappear? Delted on the camera and the computer but the computer is where it went to the recycle bin which I cant find?!?
