If you mean the thumbnails within an album on theme tab of the admin options. If you mean the thumbnail that represents an album you change the size of that also with that option, they are tied to the thumbnails. But you can of course independed sizes for thumbails and album thumbnails but you need to modify you theme with these functions for example:

http://www.zenphoto.org/documentation/functions/_template-functions.php.html#functionprintCustomAlbumThumbImage
Thank you, Acrylian. I didn't know that is posible to resize the album thumbs in the administration panel.
I'm sorry...
Can you help me in other quickly question?
I don't have in my server the gettex support and I can't to save the album description text. I can't add description into the galleries. I make the album description text and save it, but when I refresh the browser there's just the gallerie name like description again.
There is conection?
Can I to call, for example, a inside or outside description.txt?
Congratulations for you great job, acrylian, and for sbillar too!
This script is the best of the best in web.
Thank you, but we better not forget our project leader trisweb who created Zenphoto in the first place!
Actually descriptions are not depended on gettext support. That is only needed for translation/multilingual support. Zenphoto should work without that.
Do you use the admin pages or the inline editing on the site itself? We will need more info about your install like zp version, mysql, server etc.
