CSS: create white glow around image

How can I create a white glow as the border of an unknown size image?

Use simple CSS3 (not supported in IE<9)

img
{
    box-shadow: 0px 0px 5px #fff;
}

This will put a white glow around every image in your document, use more specific selectors to choose which images you'd like the glow around. You can change the color of course :)

If you're worried about the users that don't have the latest versions of their browsers, use this:

img
{
-moz-box-shadow: 0 0 5px #fff;
-webkit-box-shadow: 0 0 5px #fff;
box-shadow: 0px 0px 5px #fff;
}

For IE you can use a glow filter (not sure which browsers support it)

img
{
    filter:progid:DXImageTransform.Microsoft.Glow(Color=white,Strength=5);
}

Play with the settings to see what suits you :)

Works like a charm!

.imageClass {
  -webkit-filter: drop-shadow(12px 12px 7px rgba(0,0,0,0.5));
}

Voila! That's it! Obviously this won't work in ie, but who cares...

@tamir; you cna do it with css3 property.

img{
-webkit-box-shadow: 0px 0px 3px 5px #f2e1f2;
-moz-box-shadow: 0px 0px 3px 5px #f2e1f2;
box-shadow: 0px 0px 3px 5px #f2e1f2; 
}

check the fiddle http://jsfiddle.net/XUC5q/1/ & your can generate from here http://css3generator.com/

If you need it to work in older versions of IE, you can use CSS3 PIE to emulate the box-shadow in those browsers & you can use filter as kyle said like this

filter:progid:DXImageTransform.Microsoft.Glow(color='red', Strength='5')

you can generate your filter from here http://samples.msdn.microsoft.com/workshop/samples/author/filter/Glow.htm

Depends on what your target browsers are. In newer ones it's as simple as:

   -moz-box-shadow: 0 0 5px #fff;
-webkit-box-shadow: 0 0 5px #fff;
        box-shadow: 0 0 5px #fff;

For older browsers you have to implement workarounds, e.g., based on this example, but you will most probably need extra mark-up.

late to the party here; however just wanted to add a bit of extra fun..

box-shadow: 0px 0px 5px rgba(0,0,0,.3);
padding:7px;

will give you a nice looking padded in image. The padding will give you a simulated white border (or whatever border you have set). the rgba is just allowing you to do an opicity on the particular color; 0,0,0 being black. You could just as easily use any other RGB color.

Hope this helps someone!

You can use CSS3 to create an effect like that, but then you're only going to see it in modern browsers that support box shadow, unless you use a polyfill like CSS3PIE. So, for example, you could do something like this: http://jsfiddle.net/cany2/
