Netscape will allow you to Change the Size of an Image.
"Click-on" (using the Right Mouse Button) the Image you wish to "Resize".
Choose Image Properties.
Refer to the Dimensions Height and Width
Fields (above)
The example (below) is Resized to:
Height 25
Width 250
"Click-on" Apply to "see" the effect, ("click-on OK when finished resizing)
FYI..., The Original Size Button, restores the Image to it's "original" dimensions.
This feature is of Limited Value.
The Quality of the Image is "greatly diminished". It is best to use good "image processing" software such as Adobe Photoshop, but this method will Reduce (and Enlarge) Images in a pinch!
