Photo Gallery thumbnails

Hi!
I am trying to create a website and i have most things sorted out except for the photo gallery!
I have many many pictures to post but the only thing i can think of is linking each picture individually to their thumbnails (which i also have to link manually to the gallery page!) I found a template for the gallery pages and I have been using Dreamweaver to tweak stuff. All I can think of is linking the thumbnails that i created from the larger images individually to the photo gallery template. Is there a faster way to do this? I saw something about automatic thumbnail generators that do your gallery for you and sort everything out when additional pictures are uploaded in the future.
Any help would be greatly appreciated!!!
Thank you very much in advance =)
Sincerely,
B

Do you mean when a thumbnail is clicked that it just opens up the larger image? There is the Lightbox option…or one of its many alternatives?

Thank you kindly for your help and attention on this matter!
I will look at my options and tell you how it goes!

Photoshop has a generic web gallery tool. This should be good enough to get you started and edit the styles from there.
