Hi Christina,
Good work, looks very nice! There are still some images in the wildlife adventures where I get access denied, like this one:
http://www.pbase.com/rollosphotos/image/95429848 - did you make this a hidden image ?
Also in IE7, the thumbs on the front page are spaced very far apart because the table has a width of 90%, dunno if that's the look you were going for but seems more natural in Firefox where the thumbs are closer together.
regards,
Flemming
