full url of image showing

Hello

When I go on the website, http://www.stepsbyfaith.org and make a comment on a photo.. I then go to FB, and when I click the image a new tab opens and that image comes up.

Is is possible to have these options.
1. In FB, when the image is clicked, bring the visitor to the page/post the photo is on?
2. If the image does have to come up, use either a short or or permalink? I dont like that the full url is available.

Thank you!
