About displaying images on web
in [Dreamweaver]

From: LarryM on 1 May 2010 08:12 To get a better understanding of this I made a little test page. (This test page might have been erased at some (later) time). See Http://www.arxfoto.se/test/zoomtest/zoomtest.html This is just a quick test, For a quick comparison: Zoom up this page to 200% and compare IMAGE 2 and Image 3. IMAGE 2 is scaled down and Image 3 is shown as original. Image 3 (and Image 1) has detoriated but IMAGE 2 still keeps the sharpness because of the scaling down. If you are extremely interested try to follow the directions on the page. And of course there is the cost of a larger image file. /Laary

It was really just an example of the auto-code you'll get by scaling the image within DreamWeaver using the mouse. If you're entering numbers manually, in either the porperties / inspector panel or the code itself, then you could try using percentages instead of pixels. e.g. <IMG SRC="Images/MyImage.jpg" WIDTH="75%" HEIGHT="75%"> Helpfull Harry :o)

And this size is as if the image had been displayed in the full size in zoom 100% ! This strange effect is now illustrated in Http://www.arxfoto.se/test/zoomtest/zoomtest.html /Larry >
