I don't know where your jpg went - I didn't actually look at it myself. Perhaps if you upload again I can take a look at it this time to get a better idea of what you want to achieve.
As for web links - I'd like to see a link to the page that you want to include, and a link to the including page if you've done any work on it yet.
My impression is that you are only going to be able to achieve your objective by using some browser-intensive javascript, but let me get my head around what you're doing first. Definitely sounds like a job for PHP...
By the way, if you are coding both web pages, can't you just cut and paste? Why the need for an IFRAME?
