When people give rep points or 'like' your picture, you'll get a notification. In the notifications tab, there will be the post link.

Like so:

"You received a positive reputation by "this person" for "this picture". Due to this you will receive x reputation points."


When you click the part where the link is, does it give you an error? Or, where does the link lead you to?

Well ... then click the link.

It will take you to the picture where the comments were made and stuff.
