Any question answered...

Not now that you've hosted them on Flickr. Should've had your own web server, then you could inspect the logs.

Possibly a google search for the url of your Flickr home page will bring up a list of sites which link to anything in your Flickr, then narrow it down with relevant search terms.

I have my own website that they're hosted on, it has all my important stuff on. I have a flickr too, its a handy back up, I also use it for semi important things. I also have a photobucket account for unimportant things.

Is it tagged with any potential porn word?

It's a photo of:

1. a cat
   
2. sunset
   
3. tits
   

4. your breakfast taken with a Polaroid

5. a girl bouncing into her jeans

Its a photo of some pills, not even tagged
