Hi Andy Dingley,
Thanks for the detailed guidelines.
my content type are image file types: .bmp,.jpeg,.jpg,.gif - animated
too, partially .wmf
i use ms-internet explorer 6.0, on some web sites. when an image file
is displayed on it,
sometimes a "4 options small bar" - save file, print file, email file,
open my doc's folder - is displayed on the upper left side. sometimes,
a resize image thumb is displayed on the image. the reason is for
posting this topic is, because not all clients use ie,
so i want to have a more clear controled switch on my web page.
Maybe you have a sample code page for your example?
