I was under the impression that if you wanted to create a customized popup in TypePad (say, for an image of the San Francisco Giants' Mays Field), you had to be using an Advanced Template in order to have direct access to the CSS where you'd do some funky technical shit.
Not so, dope.
You can create a popup of any size and with a range of features (with or without scroll bars, for example), using simple code right in an ordinary post. Here's the code for the popup above:
<a onclick="window.open(this.href,'_blank', 'width=600,height=350,scrollbars=no,resizable=no,toolbar=no,directories=no,
location=no,menubar=no,status=no,left=0,top=0'); return false" href="http://edbatista.typepad.com/vivabatista/images/2005/02/
(Note that there's a line break between the 'directories' and 'location' attributes to get the code to display properly here. That break must be removed to make the code work in an actual page.)
Now, just because I was able to get it to work, don't think for a minute that I really know what I'm doing. I don't fully understand all the attributes, or what'll happen if you change 'no' to 'yes', but it doesn't really look all that tough to figure out, now, does it?
