The real advantage, to me, of PictureView is that it saves my time.

All of the pages download with 15 thumbnails on each of them, and you only enlarge the pictures you like.
if you don't like any of them go to the next page.

Evven a 28-bit modem will download and show 4 pages or 60 photos per minute.

This is as fast as even a DSL connection can show them, minus all of the hassle of clicking in each single line.
A 56-bit modem is even quicker.

To me it is worth 15 pence per day.
