The galleries created in Sava do not produce any alt text on the images. I dont see anywhere in Sava where you can insert alt text for the images so you will need to edit the /default/includes/display_objects/gallery/index.cfm file and add them.

You can add an empty alt attributes to the IMG elements there however that would means the page will still not validate so the best option is to add the image summery and strip out the HTML. This works ok if you dont have a long summery for the image.

This is something that will need to be address in Sava as with the latest accessibility laws alt text has never been some important.
