Sending Larry an email is the right thing to do. He'll contact you with the details.
The hosting site that crazed_dolphin mentioned was PhotoPoint. Overnight they just weren't there! It caught alot of us by surprize and lots of folks lots all of their pictures. Larry was one of those users who was using PP at the time. As a fellow photographer, he joined us all in trying to find another free site...there were about a dozen of them at the time. Slowly but surely most of them quit allowing you to post a single picture to another site, they required you to link to your whole album. The next thing we knew these sites we requiring everyone to sign up on their website to even look at the albums. And/Or as mentioned, the albums owner has to make it a point to list your email on an approved list.
With encouragement from alot of photographers, Larry decided to start his own hosting site, designed BY a photographer FOR photographers. Most of us weren't hunting for something free so much as we wanted something dependable. Larry has provided that for us.
As for the spam....the first time I signed up for Imagestation to look at someones pictures, I had spam from them and Sony with just a few hours. Luckily I had opened a Yahoo.com email just for that registration site and never used it anywhere else. In just a months time, that account was getting about 50 spam emails a day from all over the place!
