Dissolving landing page

 Does anyone know a way to make a page link to another page within my website in a way that is not just qucikly switching to the other page.

I want to have a landing page with an image and when you click the image the page sort of “dissolves” into the main front page of the website and the image dissapears.  

I am very new at this so any help would be great.

Thanks

Is it possible to use, for example a query string at the end of the URL and then use Javascript to make the image go away.

This explaination probably is vague. Could you give us a bit more background on the technologies used? Then we can come up with more specific instructions and ideas.
