Idea: a new HTML attribute on the IMG tag for zoomable images

Often is stated that more megapixels on the web is not so useful. Computer screens are not big enough to display all those pixels. Of course screens get bigger in time. But the size of computer screens does not increase very fast. It will also have a reasononable limit. Most people would not want to sit at screen of several square meters.

10 million megapixel camera
10 million megapixel? This must have been a mistake.

But what about zoomable images? We have them all over already with maps that are made available by big companies like Google and Yahoo. What about a new attribute to the <img> tag, that will automatically add zoom functionality to the image displayed. Wouldn’t that be great?

Something like <img src=”myphoto.jpg” width=”300″ height=”200″ zoom=”yes”>. Then when the actual photo is 3000 x 2000 pixels this automatically displays a zoom bar on the photo which allows step-by-step zooming in to the actual pixels. The area in which the image is displayed does not grow bigger while zooming in. But it should be possible to move the zoomed-in photo around in that area with the mouse. Exactly like the different map-applications work.

Of course this effect can be created now too, but it requires lots of (javascript) coding and it requires that for each zoom level a new resized image is created and placed on the server. That’s not really easy.
