I've identified some common crystal forms for pyrite on this web page by photographs. In order to let your webpage load quickly, I've set the displayed photo sizes to 320x200. If one of them interests you and you want to be able to read it legibly, then download it by right clicking and you will get the full resolution photo.

To examine one of the above at high resolution (for example, to print, or if you want to see the little numbers on the faces), you can click on the images directly here: A_M
B_M
C_M
D_M
E_M
F_M
G_M
H_M
I_M

I've also put the unmarked photographs up here:
A_U
B_U
C_U
D_U
E_U
F_U
G_U
H_U
I_U

It's at least conceivable that someday I'll learn enough HTML to make this more convenient.
