Thank you ROSCO for viewing my suspension bridge and taking the time to be
of assistance by responding to the BrickShelf questions.
The pictures on BrickShelf are uploaded from my folder of scanned pictures.
My pictures look fine and I'm very impressed (almost to the point of
giddyness) with the quaility of the scanned images in my folder of those
pictures. The images on BrickShelf are so blotchy (except for the first
one.) Could it be with the upload from my folder to BrickShelf?

Thanks for the link. I'm starting to get discouraged having to do work to
have pictures on BrickShelf.

Here is a link to the Deer Isle Bridge. Check out the rise & fall on this
real one!

I started to add the folder of cable-stayed pics to BrickShelf and I'm
experiencing the same poor oversized quality as the suspension bridge
photos. I'll try my best to have presentable images to view.

PS what does the "8?" mean?
