Where is the Basic photo resize in iPhoto feature

Recently, I found a feature that let me resize photos in Iphoto to various preset sizes and easially export them to my desktop or wherever. The sizes were real baisc, 2 x3 4 x 6 8 x 10 etc but using the custom feature I could resize them perfectly for web photo requirements on Fiverr.

It seemed the setting was on the right margin in Iphoto to resize the images and I did about 8 of them. ...Now I cannot find that feature-

Can anyone help me locate it in Iphoto?

Many thanks-
