As seen above, he's just accessing a smaller image file, not necessarily a reducing it via html.
Using "View > Source" in the IE toolbar, we can find his line of html, which looks like this:
img src="http://i15.photobucket.com/albums/a351/ryanfaulkner1/P1010438.jpg" </img
(I took away the opening and closing brackets, of course.)
With some tweaking, I made the image display at 1/4 the size, by specifying each side half as small.
First, find out the dimensions of the image.
You can do this by right-clicking the image in IE and going to "Properties."
In this case the image is 284x213.
To make it quarter-size, I re-wrote Ryan's html, and specified the dimensions.
So the line now reads as follows:
img src="http://i15.photobucket.com/albums/a351/ryanfaulkner1/P1010438.jpg" width="142" height="106"
Don't forget your opening and closing bracket thingies.
