Version Bronze is for folks with very small databases where your determining all the image dimensions and populating height and width columns is not too onerous a task. For all other situations, version Gold offers the distinct advantage that, given the imagepath and imagename, it determines image dimensions on-the-fly at the server before the ASP page is fed to the client browser. Both gifs and jpgs (actually pngs too) are read, saving you from an often impossible chore.

The Examples page gives you some idea of just what this SSB can do.
