Thanks for the additional information. I agree that hosting images is becoming more affordable. I use HostGator and have only 10GB, but their new accounts are throwing around 200GB like its nothing. Someday they'll upgrade my server and I'll get more space. These additional details help to get more interest.
You stated earlier that traffic is your goal, what do you plan to do with it? Referrals, adsense, both. Don't share if its a secret 8)This is part of a question

We, I mean, Internet-aware photographers, are approaching the point, where hosting becomes REALLY affordable. In the same time, there are stock photo agencies, and their services improve, too.
So it is a mater of personal choice, which way to go. One can have his own web site, or not, if stock agencies provide what he need. Or both.
Of course, having a web site requires some knowleges, but it is far from rocket science. The reward is quite obvious: you are in control of the look and feel of your little business...
So I decided to choose the second approach, mostly because I have a correspondng background, and I don't have to learn anything

I know my English sucks a little, but fortunately, it does not affect my programming skills.
And then, after I have all the tools I need, I came to realize, that some of them can be made public. Why not?
Though, _base_d on the poll I run in this forum, people do not really want it

Services like that are not my invention, of course, but usually, they target a different group of users. For example, Google has an exellent image collection, and still, try to look there for a stock photo of given size, price and subject, and you'll have to deal with too much "junk". So, I believe, I have my niche.
As for your second question, I have some experience in creating small eBusinesses and SEO. This experience, together with businesses themselves, can be found at ecommerce.snowcron.com and snowcron.com, correspondingly. Technically speaking, it is (and my photo directory, that we are discussing in this forum, belongs to this category too) all about an idea of creating the "unmanaged" business. You create it, and you go to South pole. And when you are back, it still works.
The "automating sending PayPal 'thank you, here is your order' emails" tool is at snowcron.com/digital_sell.htm, and finally, the prototype of a service that this discussion is about, is not yet available. It will be, within 10 days, as photodir.snowcron.com
So, to your question: I use my sites to send visitors to my other sites. It works fine, so even if you do not use goods from one of them, you'll probably see the _link_ to something you like. A micro portal.
