By having multiple pages, you are more likely to have multiple-references in search engines, i.e., more 'hits' on your site when someone searches for relevant words. If you are including pictures, use smaller pictures. If you want a larger picture consider having a small picture that is clickable to a bigger image, at the discretion of the user. Try to include a picture of something especially interesting or unique to your market. For example, rather than a generic close-up of peppers and carrots, include a picture of an unusual colorful looking stall.
Some search engines look at just the URL and title.
This will increase your chances of being 'hit'. It looks more professional to have a title, and it also provides more information to help the user decide if they actually want to go to your site. Remember, someone may start on a sub -page of your site, through a word search. NOT to the previous page of your site. You want to encourage them to look at your complete site, not just the particular page they start out on.
