imgsize.gp

• v 1.0 - first version
• v 1.1 - fixed path building - now using File::Basename
• v 1.2 - now supports PNG in addition to JPeG and GIF

In its simple form, img() returns
<IMG src="aImageURL" width="xx" height="yy">
if aImageURL results in a local URL, and the file is recognized as a .GIF or .JPeG file. xx and yy are the width respective the height of the image, as read from the file.

In its 2 parameter form, img() returns
<IMG src="aImageURL" width="xx" height="yy" alt="aDescription">
where aDescription is the alternative text that is shown as a placeholder before the image is loaded, as a tool tip when the mouse hovers over the image, or in textual browsers such as Lynx.

The three parameter form of img() allows you to specify additional attributes :
<IMG src="aImageURL" width="xx" height="yy" alt="aDescription" aAttributes>
This is usefull for example when you have a clickable image and want to have the attribute border=0.

<!-- _GP_ img("sample.jpg") -->

Last but not least, the three parameter form
