Batch huge mass loading by directly writing into the database

[phunsoft]

I've got a site with a really large gallery (not Phona Gallery), some hundred categories and some thousand images. Unfortunately, that software does not scale well. I'm loogking into switching to another software and am thinking of Phoca Gallery.

I wonder if it is feasible to load the DB tables pfx_phocagallery, and pfx_phocagallery_categories from a converted export of the tables from the current software. Will Phoca Galley generate the various smaller images upon first access?

I would like to avoid loading all categories and images through the usial interface. It's just too many.

Any experience regarding performance and scalability with that large a gallery?
