IE Jpeg opacity?

[Keith Hughitt]

A little off-topic, but, does anyone know if it's possible to set the
opacity of jpeg images in IE7+? For firefox, the css "opacity"
property works fine on most image types including jpegs. On IE,
however, the equivalent filter, "(filter: alpha(opacity=...)," only
works with PNG images.

Anyone know if it's possible to get the property to work for jpeg
images as well?

Thanks,
Keith

As per my test, the following should work on MSIE6 (XP) and MSIE7
(Vista):

border="0"
style="filter: alpha(opacity=25)"
Maybe MSIE could have problems if your JPEG-file has an unusual codec
(?)

Hope this helps,
