First post so please be kind.

Been playing around in the demo and there is so much to see that I seem to have lost one of the major things I might require for this to work on a particular site. Please help: I thought I saw a way of creating a small image gallery, which could go in the third column of my template enabling me to add say 3 images from the server using a particular image template (from what I remember) without having to create thumbnails and adding links to the larger image from the wysiwyg; so basically all I'd do is choose the images, choose the template/layout and press save..... page relevent mini-gallery sorted.
Could somebody either tell me I'm tripping, thinking of something else or point me in the right direction?
Many thanks in advance and nice to meet you all.
Regards
Jon
