The first thing to consider is that a search engine does not understand photos at all - it merely collects keywords about a photo from various places detailed here, as described below:
- The image filename
- The alternate text where the image is shown in a page
- Text around the image on a website (captions and text of the page)
- The website title and domain name.
Filename
The image filename is worth checking - it can be obscure (your logo, for example is called New-Logo-1 rather than LivingArt-Logo) and most people aren't aware of the name as it's never shown to the user.
Alternate Text
The alternate text is embedded into a website for each photo (you can check this by right-clicking on any image in a web page and selecting "Properties" from the menu).
this text should be a quick description of the photo (in your case, "LivingArt Logo" or "LivingArt horse skeleton by Samantha Elmhurst" might be appropriate)
This alternate text is doubly important as blind users, people with images disabled or unavailiable see this alternate text instead of the image - so your logo, for example, would look nice normally, but have no impact on someone without any image support as the alternate text is missing. They'd know an image was there, but not what it might have been. We can add alternate text to your website's images quite easily, as it's just a matter of adding an attribute to the existing image tag in the web page, which can be done without modifying the structure of the website.
Website Text
Text around an image on a website also can contribute keywords for an image's listing in a search engine. This isn't as highly rated for a keyword as alternate text or name, but can add more information about an image. For example, the enormous url below (which is the same as this tinyurl abbreviation: http://tinyurl.com/2ub546 ) shows your horse-and-rider image from your front page. The only keywords attached to this image are shown in this second result: http://tinyurl.com/325nst (a google image search for "livingart copyright" to bring it to the first result) - these keywords were taken from the front page, near the image, and aren't really intended to describe the image so much as the entire site - but the search engine doesnt know that, and those words are the only information near the image.

Title, Keywords and Domain
The website title and domain name can lend something to an image's keywords - note the images which have your domain name as a keyword, as they're shown on the front page and are assumed to be most important: http://tinyurl.com/2qvxyu

All this information and techniques are part of that's termed SEO (Search Engine Optimisation) - the never-ending battle of every commercial website to be first in the rankings on a search engine for the keywords for their industry.
