any resizing needs to be done server-side
The down side of this is that it places an unnecessary load on the server. Take for example a page of thumbnails resized by the server from larger images. Server resources are consumed for every image resize which needs to be performed as the page loads.
So if you have 1,000 concurrent users loading one thumbnail page you can have resource issues and how many more thumbnail pages are there to spider and explore? I used to use resize server side and used that method for several sites including client sites (home grown shopping cart) that included shopping carts and listings for 1,000s of items and their images.
Now I leave image resizing to the end user. Better to use their computer resources rather than to stall a server.
