Sometimes I can get the contact's profile picture and sometimes I can't

When using GetProfilePicThumb sometimes I get de URL and sometimes not, from the same contacts... Any idea to how can I resolve this?

I cache pictures on my side =)

Ok, thanks for your reply, no doubt this could be a solution, however I would like to understand why this happens.
