Go to Fototime, click on photo you want to post, when it opens in a new window look to your left, in the column of options, click on "create link".. When the link shows up, highlight and copy the one on top, Go to the place where you want to post and type [img]
Paste link next, then type {/img} but use the brackets [ ] instead of the { }
Make sure there are no spaces. That's it..
