I'm using jQuery Supersized to display a full screen background slideshow on my blog, and I'm using mobile detection to serve a smaller version of the images to mobile devices so it will load faster.
Which option do you think would be better?
- Use TimThumb to dynamically resize the image size and jpeg quality
- On upload of the image, create another version for mobile devices e.g. myimage_mobile.jpg
Also, how do these conversion options compare in quality to resizing in photoshop?
