Cindy have you uploaded clean unaltered code from our members area and are using that on your site because I show you have hacked files that are not our default code.
I think alot of your confusion comes from your edits of files. Lets take this if I hit my photos on my site it takes me to my photos which you can see. - ReefTalk Gallery
I hit it on your site and it goes to the profile page on your page so definitely something strange. http://www.cpcmag.com/gallery/u2032-chuck.html
You really need to download the photopost code from the members area and upload all the files except the two config files and install or upgrade.
You will then be running clean photopost code and I do not think you will have any issues as our files will be working as they where intended to work.
