I've posted a link to this site before, but it's been awhile

There are thousands of pictures of Las Vegas, accompanied by historical information. There are various ways to see the photos...you can just scroll down and look at them in the order they were posted (for the most part, he posts a picture a day, every day). You can click on the Archives link and get thumbnails of everything, and just click on whatever catches your fancy. You can look by location...strip, downtown, etc. You can type a casino name, or a year into the search box...

Have fun with it!
