Well, there is this page I made for somebody ages ago:

http://eeberfest.net/AbelCam/4cam.zip

It uses the Java applet for streaming. Click on the images to move Pan/Tilt. Sliders control Zoom. It isn't very pretty or fancy but it shows 4 cams on one screen and you don't have to click anything to get it going.

It uses the MJPEG streams (not individual JPEGs) from AbelCam. So, if you want the video to run forever (not require clicks to restart periodically) you need to go into each of your cams' configs in AbelCam and make sure the "No Limit" box is checked for "Max Motion JPEG Frames".

In the HTML you'll need to replace a bunch of "localhost:8080" with whatever is right for your setup.

This sample page uses Cameras 0 - 3. Each Cam Nr. appears twice in the code: once for the image and once for the slider control. Just be aware of this if you need to use different cam numbers for some reason.
