1. ISP/web hosting selection. Your telecom may offer "free" website with subscription. I've no idea what the broadband and storage limits entail, but you'll need to total your photo inventory (low res, MB or GB) to estimate near-term growth. Otherwise pay to diversify your portfolio, and avoid the GOOG and similar engine aggregators.

2. Site design. Keep it simple, static HTML layouts (One "splash", one "thumbnail" per photo), display DPI (low res, 72ppi) and hyperlink to text documents (thumnail photo) rather than "setting to fit" around a Big Beautiful Picture or messing with Javascript or applet "pop-ups".  Decide now on classification and a name convention (alphanumeric) for photo and related text inventories before executing www design or selecting a DB/integrated software package such as Dreamweaver, Flash which are meant to facilitate local PC to server updates. Incidentally, contact your ISP about remote server-side privileges and fees.

3. Purchase facility. Your choices are stand-alone (navigation bar) or embedded (text sensitive) functionality, which requires intermediate skill with HTML/XML/SQL scripts -- better yet confidence installing any one of a number of open source "shopping cart" scripts to process manually invoicing (prints from high res). I haven't looked into lately --and this is no guarantee-- but I think PayPal merchant offerings bundle these needs.
