I have many images on Google Images- but not showing up

[mja1906]

I know there are many pics of mine on Google images, as they show up when I put in various search terms.
However when I do a 'site:mydomain' search for images from my site it only brings up 1 result from my site. Whydoes it only pick up 1, when I know there are many more?

It works fine for me, coming up with 9 images (those that aren't in a folder I don't allow bots to search).
When you click on the image after using the search terms, does the "Below is the image at: ..." show your domain?
