images resize performance
Posted on 2010-11-23
I have a website written in Coldfusion.
For now, we use several images folders, with different size (1 for largest, 1 for thumbnails, etc).
I want to reduce the disk usage on the server and to improve displaying performances.
So my question is : what solution is the best in terms of performance ?
- To keep several folders with different images sizes ;
- Or to keep only the biggest images, and to re-size them according the needs.
If the best solution is to re-size them : is it better by specifying the width & height in the <img /> html tag (for instance 50% for both) ;
or to use the <cfimage /> coldfusion tag ?
Or maybe is there another solution more suitable ?
Anyway, I want if possible to remove unneeded files & improve displaying performance.
Thanks a lot
