I would like to add a word to every single uploaded photo.
Albums and images retain the original title, but were google-indexed with a additional word.

For Example

Album title = Miami Beach
Photo titles ? miami Beach 001, 002, etc
Indexed titles = Miami Beach Holiday

"Holiday" il the additional and indexed word.

Is it possible without renaming every album/photo?

Thank You

I suppose you could modify the sitemap plugin to do this. But remember that Zenphoto uses the album name, not the title as its link.
