I've tried building an image gallery using Gallery2, but the images don't look good when they are different sizes like this one: http://trip-photos.org/gallery/v/Greece/110_1071s.jpg.html and this one: http://trip-photos.org/gallery/v/U_S_A/California/Hiking/Fern_Canyon_Hiking_Trail_019.jpg.html Are there any scripts out there and automatically resize all images to one size that you specify somewhere?
try http://www.minigal.dk/ Very easy to use and setup, you can define the thumb size in the admin and the style of the galleries are really nice
Looks like that script only allows you to specify a thumbnail size, but it doesn't have a way of resizing the bigger picture.
I don't know if this resizes it for you, but it's a really cool script, and you've prolly seen it in action on many sites: http://www.slideshowpro.net
