Gallery system setting that allows to define number of thumbs on one page

[exside]

I would like to be able to set the amount of thumbnails in an album to be set via system setting. There are cases with very unsavy clients that are totally confused by the pagination (they don't see the images on the following pages and panic =D), so it would be helpful to be able to show all images on one page (even if it gets messy...not my problem if the client is more comfortable like this)
