Hello, We have a website where users can browse photos of different categories. For each photo we are using a meta description template such as:

Are you looking for a nice and cool photo? [Photo name] is the photo which might be of interest to you.

And in the keywords tags we are using:

[Photo name] photos, [Photo name] free photos, [Photo name] best photos.

I'm wondering, is this any safe method? it's very difficult to write a manual description when you have 3,000+ photos in the database.

Thanks!
