i have a GalleryImage and I need to be able to scroll next and previous, how should I implement this in hibernate?

this is what I was thinking, having a column that holds "counter" so the first GalleryImage I insert for a given Gallery starts at 1, the next one added starts at 2, and so on and so fourth, but what if I have 10 GalleryImages and the 5th one is removed? there would be an empty spot.. so that idea is no good..

how should I do this?

I could also do a query, to give me the next object previous/next to the current GalleryImage being displayed..

I would have to use a generator that generates ids sequence from small to large.. just a thought

This is a pretty simple problem and doesn't relate too much to Hibernate.

However, I think that Hibernate's List one-to-many might help you keep the indexes of a particular set of images always ordered 0..n.
