The “prebuild” approach allows you to paginate results, assign taxonomy terms, etc:

If you don’t care about pagination or adding taxonomy terms, you could use resources.ExecuteAsTemplate then Publish.
Neither approach is suitable for new or casual users; you need to know what you’re doing.
If you can’t stuff what you want into EXIF fields, use @Welsh’s suggestion… works great.
