A little more tinkering.... To use your own logo, you have to make the album once
without your logo,
then go to that setting and provide your own logo.
The sizing issue is a classic example of a skin doing you a "favor" that you didn't ask for. It sizes the logo to occupy 60% of the page width. Unless your logo is huge, that's waaaaaay too large, so the logo gets blown up to horrible fuzziness.
The cure is to head for
Zigzag > Advanced, and enter some quick custom CSS:
.centerlogo {width: auto;}
