How to I reference my variables

Posted on 2001-07-30
Last Modified: 2006-11-17
I'm using gd functions to combine a map and a square which marks a grid reference on the map.  Here's the code (it's the entire file map3.php):

Header("Content-type: image/jpeg");
$image= ImageCreateFromJPEG("images/map2.jpg");
$icon = ImageCreateFromPNG("images/square.PNG");
$trans = ImageColorAt($icon, 30,30);
ImageColorTransparent($icon, $trans);
$width = ImageSX($icon);
$height = ImageSY($icon);

ImageCopyResized($image,$icon, $x_coord,$y_coord,0,0,$width,$height,$width,$height);

I'm accessing it from a link as follows:

<A href='../map3.php?x_coord=760&y_coord=189'>V33</A>

The problem is that I have very little control over the result because it is just an image, no html.  I want, for instance, to be able to add a caption to the window title bar, add more html to the result, scroll to where the square appears, add a close button inside the window, remove the margins, but I can't do any of these things.  I've tried using an html file which includes the image tag <img src="map3.php border="0"> but it's not picking up the coordinates which position the square.  

I've also tried using window.open and window.showmodaldialog.  These give me greater control but I cannot, for instance, caption the window or add a close button or scroll to where the square appears.

If anybody can help I'd be very grateful.

How about this :

link to the new window with :

<a onClick="w=window.open('imgload.php','imgload','scrollbars=no,width=760,height=189')">V33</a>

and have a php script that loads the image, provides a close button and removes margins called imgload.php :

<title>Your caption</title>
<img src='../map3.php?x_coord=760&y_coord=189'>
<p>Click <a onClick='self.close()'>here</a> to close this window.</p>

Hope this helps,
