About displaying images on web
in [Dreamweaver]

From: LarryM on 29 Apr 2010 07:42 Some thoughts about displaying photos on the web: With todays high resolution screens you may have to zoom the browser to say 150% to get the site to fill up your screen. Is there any way that you could preserve the sharpness in an image even if it is being enlarged? You could imagine that it could have a higher resolution "embedded" that was put into effect at enlargements? Meaning that in zoom 100% the image would be sampled down to that size (72 ppi?). Hm, formulated in another way: Could you force an image to be displayed at a fixed relative size (for instance 50% of the display window or of the table width) independent of the ppi value? Thanks in advance, Larry

It's a annoyance for users on dial-up or data-capped / charged plans to have to waste time and data downloading extra information they won't see. You'll see this a lot on novice websites where they put a massive image straight from their digital camera on the website and then scale it down on the webpage, or lazy web developers who use a webpage-scaled version of the big image as a clickable "thumbnail". Helpfull Harry :o)

I am a photographer. My web visitors most likely uses broadband and I don't plan on putting in megalarge images. My visitors also are likely to have high resolutons screens and are likely to see the web browser using some zooming in, say to 150%. When doing this zooming the images get a little bit blurry which is a pity. I am looking for a way to preserve sharpness even if the image is somewhat zoomed in. My little test with Photoshop made images which then are put into a Dreamweaver built web page seem to fail. The images are displayed in 72 ppi mode, the 144 ppi is just double as large as the 72 ppi image (same size in inches). You don't happen to know how I could preserve sharpness when zooming in images? Even if you basically don't like the idea...? Maybe you could say that this is also about how to design a website for a certain (normal to low) resolution but which also can stand a zooming in without loosing the (image) quality. Is it possible? /Larry

The normal method would be to have a standard, smallish photo as a link with a "click to download full resolution version" and possiby the file size for information. Link one to the other, open in a second window, and the job's done. You could even do it with thumbnails offering 2 sizes for download but, in your case, you might want something bigger for the first viewing. This gets round the problem people may have in some areas - yes, in big towns and cities too, of extremely slow broadband. -- duncank

Hi Duncan, let us for the discussion say that the visitor uses zoom to 150%. ANd let us say that downloading time is no issue. The technical question is: Could an image which in 72 ppi is 10 inches wide be displayed with a width of 5 inches on a web page? /Larry |
