SEO of Photography Site?

Is it worth my writing something and hiding it off page for each?

Hiding contents can get your site penalized by Google.

OK good to know.

Why do you think only the “about” page is appearing then and what can I do to help matters?

Thanks!

but I wondered if pages having text content helped?

Yes, pages that have text content helps.

OK, as it’s a photography website I’d rather not add text to the image galleries. Do you have any suggestions on what I can do to help the homepage appear when I search for his details?
