I'm planning for a site which will use a number of small image elements, which leads naturally to looking for first-load speedups by using sprites.
Since the site will be responsive, it will need the sprites to resize.
- One way would be to let Craft do the resizing; might work well enough.
- the offsets would also be very nice to find re-aligned with the resized sprite locations. I think I am probably talking about a feature request here. Maybe it could be as simple as a conversion function, cached results or not.
- another possibility would be to allow Assets to specify their own non-generated images for given Transform labels. Maybe by a middle-extension that named the tranform, if not a tranform folder solution?
Ok, I think this is all dreamland for now, but might spark some thinking. I'm considering it because I think I'm realizing that the delay times for later than first images which show even on a Pingdom are probably due to limited sockets for browsers, or a modeled equivalent in the monitoring service if they are not just using Webkit contents for this.
Something to think about, or if someone has an answer I don't know about.
