You can just use a plain button, instead of an image. It looks just like a submit button.

<input type='button' onclick='doSomething()' value='click' />

A normal button like I mentioned above has 3D effects just like the submit button (on most platforms, anyway).

However, you could dynamically change the src of the image to an image that looks like the first one, except that it's a different shape or color.

<input type='image' onmousedown='this.src="down_image.png"' onmouseup='this.src="up_image.png"' src='up_image.png' />

Let me know if either of these is what you need.

HTH,

There are only two stupid questions: the one you don't ask, and the one you ask more than once :-)

It is not what I want.
I have three buttons:
     a submit button
     an image (up-arrow): when clicked, it goes up a list
     an image (down-arrow): when clicked, it goes down a list.
When the page is loaded, the focus is on the "down-arrow" button.
Now, I only want the down-arrow to change to "another-down-arrow" when the focus is on it.

I think I'm still missing something. Your up arrow, for instance. You want it to look different when the focus is on it, or when someone is clicking on it?

You can do onfocus, but usually people go for the onmousedown and onmouseup effects.

<input type='image' src='up-arrow.png' onfocus='this.src="another-up-arrow.png"' onblur='this.src="up-arrow.png"' />

Now do I understand?

That's right!!!!. Thank you so much!!!

Now, instead of vchanging the shape of an image, how can I do almost the same thing but change the color?

Just change another-up/down-arrow.png to have a different color.

I am sorry to bother again but I don't know how to modify the color of my image!!!

How would I do it ?

What program did you use to create the image?

I did not have to create it, I already had a .gif. What I needed were 2 arrows in 3D (up and down). I would be nice to have the same one in red when the focus is on them.
