Here's the idea.
The software is uploading one image at a pre determined interval. Let's say 30 seconds.
You need to display that photo (image.jpg) on a webpage.
You can build a webpage and put that image location (something like webcam/image.jpg) as the source of image and then tell the webpage to reload every 30 seconds.
You can do this with only html, or it looks like they have a java.class that will do this. In which case you will need to build a webpage with the java to reload and the image.

For your ftp host I would look at the FAQ section of your webhosting service.
something like this should work
login to account which username is [email protected] and ftp server is at ftp.domain.com
Look at your webhost faq's should give you this info along with ftp path.

If you need help with a webpage etc. click on my name, and send me an email or provate message. I can put something together for you to test.
