Looking at Michael and Craig's suggestions, you can do two things:
1) download the html and look inside for the reference to the image. All browsers allow you to have a look at the html (source). To do this in chrome simply click ctrl-u and a new page will open. In html (this might not be the case), images are tagged with "<img". Read any html tutorial for more info. Parse the html file as Michael said to locate the image and maybe you'll be lucky. It could be that the image is "hidden" in the code...

2) Craig suggested using wget. If you're on linux, that should not be a problem, but if you're on windows you can look for a wget for windows (google that and you'll find some free solutions). From idl you can use the spawn command to interact with the shell and launch wget and retrieve the images.

Good luck!
