[Rets-dev] On bandwidth

[Paul Stusiak]

While there are many possible optimizations, photo servers I have worked 
on before do not inspect the images for such useful values as the X and 
Y dimensions of the image. I'm not sure if such information would be 
available generally.

One thing that I have seen implemented and we may want to consider it, 
is to have a series of pre-scaled images to meet the purpose - 
thumbnails for a quickview or slide show, mid-sized for web viewing and 
higher-resolution images for printing or image-only inspection. Please 
share your experience with this - is this common in your location as 
well? Perhaps we should codify this into the standard.

The semantic discord should be resolved. Thanks for pointing this out. 
There was an effort made to make the Media package more than just about 
pictures, although the majority of the media will be pictures. I'll put 
it on my list of changes.
