<button> as Submit button

[bowers01 +]

Hi,
I am using this code

<button type="reset" style="border:none;background:transparent"><img src="{$smarty.const.URLS}/templates/{$smarty.const.MAIN_TEMPLATE}/images/resetbtn.png"></button>

but because it is actually a button when the background:transparent is taken away it looks like http://everythingsfree.org/image//im...8217button.jpg
So even when its set to background:transparent the button is hidden but it still is wider than the image and is clickable. How can i make it so the actual button is the width of the image? I have tried using <button width="116" type="reset" style="border:none;background:transparent"> but it does not change anything.
Any ideas?
Cheers

never mind just worked it out, used <button type="submit" value="submit" style="border:none;background:transparent;width:11 6px">
