How on earth do I do this?

[Greenstar]

Hi, folks. Ok, I've finally plucked up courage having lurked and been inspired by your words/advice. I'm going to create a website for a friend who runs a gym. Basically, I want a black background and one main image in the centre, with three clickable points. What I was hoping someone may be able to help me with is how big should the image be? I'm doing it in photoshop and then will figure out how to get it into HTML, but the dummy is in photoshop.
Where do I go to from here and how do I know that it is the right size? I created it at 300 dpi and the entire image is 764 X 615 pixels. Is that too big/small? I figure if it's too big, I can always resize, but if I want to make it clickable and then make it a site that doesn't take a million years to load, what do I do next?
Thank you, guys...I love this forum!!!

PS: an example of what I'm trying to do, though nothing liek the design, but the concept of an image that is the portal into the website can be found at: only thing is I don't know flash, so it needs to be done in html...

Computers only handle 72dpi, so 300dpi is way too big. 764 is fine for the width, but it shouldn't be more than 450px (being generous here) high. As for the clickable stuff, check this link out: http://alistapart.com/articles/imagemap
