grab imagepath with regexp

[kasparloog]

I have the following problem:

I need to extract imagepath from <img src="imagepath"> but the image path must not be http://SERVERPATH/image.php?id=x

I know how to grab the image path:
<code>
eregi("<img[^{>]+src=\"([\"]+)[>]+>")}
</code>
but how can i make the ([^\"]) part not to accept the http://SERVERPATH/image.php?id=x
