I'm working with a Realtor who needs to create thumbnail images of properties being listed on the web.  The thumbnails are linked to a larger version of the same image. 

I looked at a program called Easy Thumbnails and it LOOKS good to me.  But, I see many other thumbnail PROGRAMS are available; for example, http://www.sharewareconnection.com/titles/thumbnail.htm

Just wondering whether any of you are familiar with a thumbnail program that you like. Well, I haven't used any of those but it's fairly simple to create your own if you are using PHP for the site with some kind of admin back-end.Thanks for the reply, KPAC.  PHP will not be involved here.  It looks like Easy Thumbnails is going to used.  Some web page editors do it for you. Frontage for one.
Some image software has photo ALBUMS that create a index page of small images with links to the full SIZE page. The program does all the HTML for you.Easy Thumbnails is a popular free Windows utility for creating accurate thumbnail images and scaled-down/up copies from a wide range of popular picture formats.
