Ah, Stu, you haven't actually READ those options lately, have you? Quoting from the page:
"Images taller than this height will be resized. Enter 0 to allow all heights, or leave the field empty to use the default value of 0."
IOW, by leaving the default set to zero, any image with any height larger than zero (which means all images) will be resized. And what I want is for every image to be resized from whatever the pixel count it, to whatever fits in the browser's normal page. "Zero" should be correct here, according to the instructions.
And no, I meant 480 vertical, as writ. VGA resolution is 480 rows tall and 640 columns wide. So any image on a standard web page, which is less than 640x480, can easily be displayed and mapped onto an XGA, WXGA, SVGA, or other high-res screen
. Depending on what version of HTML is or isn't being used, and how the page is being coded.
The problem may be in the 2002-ish version of vbulletin using an obsoleted page description. In which case, other Wintel users will be having the same problem. Or, it could be the instructions aren't clear enough for me. As LaoTsu once remarked, there are no bad students, only poor teachers (instructions).
