Image resize on demand
** Image on demand view ** I often post photos on photography fora. Most fora want you to place a link to a photo somewhere on the net, but different fora have different rules. Some fora want you to stick to a maximum of 800 pixels wide, some 700 pixel and some even strange values like 639 pixels. My own site uses 600 pixels so I end up resizing images all the time. Since I keep my originals with my gallery as well (hidden for public viewing) resizing on the fly would be a nice asset. I'm using my previous snippet to apply a slight unsharp mask for better web display of my photos. ** usage ** This snippet takes the url to my photo application which is a simple link using the pk of my photo table and adds 'width'.jpg to the end (some fora check if the link is an image based on extenstion) The view takes the width requested and creates the resized image from the original full size image or takes it from the cache for display on demand. To prevent a dozen directories I use a setting to specify which widths are allowed, providing room for several versions of the same image. Any improvements are appreciated since I'm still rather inexperienced in Python and Django.
