Author's Note: The filter calls in this tutorial are in the original Internet Explorer 4 call format. They will also work with the new filter call format instituted by Internet Explorer 5.5 or greater. Many more filters have been added as of IE 5.5. Be sure to check out the Microsoft documentation available on their web site.
Perhaps many people don't realize, but all of the visual filters may be used in your posts without any scripting knowledge whatsoever. All you need do is type the filter specification into your image or text element.
Take this basic rocket ship for example:
Here is the simple HTML that calls it. You've all seen this before in thousands of posts:
<IMG SRC="rocket2.gif" WIDTH=108 HEIGHT=108>
Let me show you how to make it look like this in five easy steps, without graphic editing:

Here are five simple filters you can try. Each creates the above effect on the rocket image, and each is done without photo editing:
Step#1
To flip the rocket horizontally, code the FLIPH filter:
<IMG src="rocket2.gif" width=108 height=108 style="filter:FLIPH">
Step#2
To flip the rocket vertically, code the FLIPV filter:
<IMG src="rocket2.gif" width=108 height=108 style="filter:FLIPV">
Step#3
To change the rocket image to grayscale, code the GRAY filter:
<IMG src="rocket2.gif" width=108 height=108 style="filter:GRAY">
Step#4
To invert the rocket's colors, code the INVERT filter:
<IMG src="rocket2.gif" width=108 height=108 style="filter:INVERT">
Step#5
To make it look like an x-ray, code the XRAY filter:
<IMG src="rocket2.gif" width=108 height=108 style="filter:XRAY">
These and other filters can be used on all images, even animated .GIFs. They can also be used on text, and I'll show you how that's done in another Quick and Easy sometime.

So quit cranking up that photo editor when you want to make a grayscale, flip and image, or other. It's unnecessary.
