Here you go...I kept the original size, just put the quality down to 80%, which dropped the files from 4 MB a piece to roughly 800 KB. I love the 2nd one of the church, you can see every freaking tile in the steeple...and the city hall (?) in the fifth photo, the fascade is just gorgeous!

And the crowning jewel for last (the digicam quality wasn't great at this distance to begin with, but size it down to...say...a desktop background and it's sharp as glass...)

EDIT: Forgot to mention, the other pics I have are just different versions of these (horizontal versus vertical, etc). There are also shots of different stained glass windows in the church, and a few more of the river. I'll upload them later!
