Hi Aishasw,
A big welcome from all of us. Suz is right that you need to be at the active member level to view other people's photos (and post your own pics too). Becoming an active member is very easy, you can read more about it on the page Suz linked to.
Here's a bit more info on the new photo viewing restriction:

I hope this helps.
