Drew,
I took a quick look at your site (this page) and there are some things you might want to address. This code:
Should be replaced with something like this:<img src="gallery_images/05.jpg" id="imgcenter">
Use a descriptive filename and useful alt text in the image tag. This will especially help if someone is doing an image search on the subject of your photos.<img src="gallery_images/hand-reading-brail-shuttered-sunlight.jpg" alt="My hand reading brail, sunlight is filtering through window shutters">
Also, you might consider conforming to web accessibility guidelines, check your pages with an accessibility checker like this and follow the recommendations.
This is all a lot of work, I know.
