Today I needed to write a pop up form that would show any image without any extra IE (or Firefox, Chrome, Safari, etc.) toolbars, etc. To get a web form to display an arbitrary image, I have a simple page that takes the URL of the image in the query string. The web form takes that string and uses it to set ImageUrl of an asp.image control.
photoviewer.aspx:
<%@ Page Language="C#" EnableViewState="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server"> private void Page_Load()
{ string file = Request.QueryString["file"];
if (file != null)
myImage.ImageUrl = Server.UrlDecode(file);
}
</script>
<html>
<head>
<title>My Image Viewer</title>
</head><body>
<form id="Form1" method="post" runat="server">
<table style="border:0;">
<tr>
<td>
<asp:Image runat="server" ID="myImage" EnableViewState="false" />
</td>
</tr>
<tr>
<td>
<input type="button" onclick="javascript: window.close();"
value="close" />
</td>
</tr>
</table>
</form>
</body>
</html>
To get rid of extra browser features and to size the popup, I call window.open() I set the height and width to values that will ensure that I have enough room for the image (I can use to get the dimensions of an image and add some buffer around the image so the popup isn’t all picture). I suppress status, toolbar, menubar. Location and scrollbars by setting them all to “0”.
feature_win.js
// declared outside of the scope of the function so it will persist on the page:
var newWindow;
function featureWin(height, width, url)
{
var lHeight = height;
var lWidth = width;
if (newWindow && !newWindow.closed)
{
newWindow.close()
}
newWindow = window.open(url, null, 'height=' + height +
',width=' + width + ',status=0,toolbar=0,menubar=0,location=0,scrollbars=0');
}
Here we put it all together.
default.html
<html>
<head>
<title>Test My Image Viewer</title>
<script type="text/javascript" src="feature_win.js"></script>
</head>
<body>
<a href="javascript: featureWin(825, 1050, 'photoviewer.aspx?file=Garden.jpg');">
Garden</a>
</body>
</html>
