RE: [APML] now what? (Image Scaling)

[Glenn Ray <Glenn.Ray@aspentech.com>]

FOA......wow. <g>

Jerry's method definitely saves space on your server, but the visual results
can be disappointing.  Images that are scaled down with HTML often looked
"chopped up" (i.e., dithered).  I recommend you display a "large thumbnail"
of about 800x600 that, when clicked, links to a larger image (or add several
links to various sized images).

BTW, Internet Explorer 6 has an option where large images (i.e., larger than
the visible window) are automatically scaled to fit the window unless the
user selects an option to scale to 100%.  Kinda cool.

Hi Tony,

Great image.

Write the html code on the web page like this:

<IMG SRC="M51.JPG" WIDTH=1008 HEIGHT=685>

But use the full resoltuion image as the jpeg. This code will force it to 
display at 1008 x 685 pixels even though it is bigger.

Do not re-sample it in Photoshop, you just jpeg the whole full res image.

Then whoever is viewing it can save it to their hard drive and open it up 
in Photoshop and see it at full res.

Of course it will take longer to download.
