Will putting images in a light box or photo gallery affect my image SEO?

[Unidev]

A website that is very image heavy and would like to enhance the user experience with a photo gallery. How will this affect the indexing of these photos? Can I still add alt. tags and title tags to these images?

Well a light box actually has the code in the site, but just does not show all the images at once.

a) should make the page lighter

b) still has all the image links, ALT, and image description (usually included with light boxes)

So from an SEO standpoint, as well as a user standpoint, this is all great!

Your light box should just show/hide images that is already within the code, so yes, ALT and Title tags are good practice.

If this is not the case with your light box, will you please provide a link or code snippet?
