I submitted a gallery to a tgp.
The pic for it has been there for a long time. I always assumed it was going to my gallery.
Today I decided to click on it. It took me to another site.
Fine I thought, it's traffic trading. But, I clicked on it like 20 more times and everytime it took me to somewhere differant (but, mostly their own gallery)

When I clicked on it in the past, it would go somewhere else only once, then the next time to my gallery.

I know it's the pic I used when I submitted my gallery, because of the way I had to crop it to make it fit the size they required.

Is this usual practice? Is it that they're redirecting for a day, then back to my gallery the next day?
Or, do they just use the pic I submitted as they want?

I really know very little about tgp's in this case.
