depends on where the photo's are stored on the computer.
try looking through "my documents" or "my pictures" first. they could also be stuck somewhere in windows or just loosly on the c: drive. they're probably .jpg files or .bmp files. just go browsing thru those places until you come across a pic, then double click on it to view. the picture viewer will then allow you to click one by one looking at all the pictures in a folder or location. to get rid of them, right click on the picture and delete. If they are really bad (questionably legal) pictures, look for and download the free file "Eraser" and use it to destroy them.
