Rockbrother,
I think that even though you have inadvertently categorized your photo under "freediving" it should still be visible in your gallery. If you want to change the category:

Go to: Home > Member Galleries, there choose your own gallery, and there is a link on the left:
Manage Photos, when you click there it'll take you to a page that has a drop down list of the different categories. Go through the categories where you have placed your photos and when they appear there's an option (another drop-down list) where you can move your photo by reassigning its category.

Click on the save changes button to confirm. There's also a delete radio button if you want to delete the pic.

Hope this helps, let me know if you have any trouble.
