converting things

[php_novice2007]

Hi,

 

I've got 2 javascript variables, var myColour = "blue"; and var blue = "./images/blue.jpg";

 

And I want to create an image thumbnail <img src=" + ??? + "width=10 height=10>

 

where in ??? I want "./images/blue.jpg"

 

But I only know the value of myColour (Its actually a value extracted from a text file). (it might not be blue, might be red, green, etc... and I have var red = "./images/red.jpg" etc..)

 

How do I do the conversion..?

 

Thanks!

function create(location){
var image = document.getElementById('img');
image.src = location;
}

And the image:

<img src="" id="img" alt="Loading.." />

I haven't done this in ages but should work(sorry if it doesn't).

so where would I call create()?

<input type="button" onclick="create('image.gif')" value="Change Image">
