Something like this should work (javascript).
var wl = window.location.href;
	wl = wl.substr(0, wl.indexOf('.'));
	wl = wl.substr(wl.indexOf('/')+2);
	if(wl === 'sub1'){
		//display image of monkey
	}else if(wl === 'sub2'){
		//display image of tiger

To get the sub domain  name server side you could use the following server variable:

url = Request.ServerVariables("SERVER_NAME")

then you can do an if statement on that variable and display the appropriate image

Sure no problem, try the code below and let me know if you have any questions.

url = Request.ServerVariables("SERVER_NAME") 
If InStr( url, "sub1" ) > 0 then 
    Response.Write "<img  src=' monkey.png' />
elseif InStr( url, "sub2" ) > 0 then 
    Response.Write "<img  src=' tiger.png' />
end if

If you have multiple conditions you want to check, just add them in the IF statement.

Thanks for the BigMonty, it sends back the whole domain, not the just the sub (which is what i would like)

not sure what you mean by this. the code just checks for any occurrence of the string "sub1" in the first if statement and for the string "sub2" in the 2nd if statement.

if you do a Response.Write URL, what do you get?

Hi BigMonty. I get the full domain. Eg

I just would like sub1 as the outcome
Big MontyWeb Ninja at largeCommented:
you had originally asked for an IF statement, which is what I gave you and should work. to extract the exact sub domain name, you can do something like:

url = Request.ServerVariables("SERVER_NAME")
subDomain = Left( url, InStr( url, "." ) - 1 )
