@Tata: I have moved your reply to the thread where it should belong (the other thread was opened by a spammer, who just copied maeg's question). However, I'm not sure, if maeg's issue is not already solved.

Indeed, images so large may not be the best idea, especially regarding slow internet connections and bandwidth limitations. I assume only a small amout of visitors have a display that is able to display 2200px horizontally, so downsizing the image seems to be reasonable. However, for displays with a higher resolution this forces the browser to upsize the image, what is generally worse than downsizing. One has to find a reasonable compromise here.

I assume that downsizing images by a large amount always decreases the image quality a bit, at least. A sharp resizer is likely to result in pixelation (especially when the images are compressed with a lossy algorithm such as "normal" JPEG); typically, diagonal lines will look like stairs. A soft resizer results in blurring. Again, a reasonable compromise is called for.
I don't know what's the best solution here, but
https://developer.mozilla.org/en-US/doc ... t_meta_tag might give some hints. Furthermore, scaling the image server-side (see
http://adaptive-images.com/) might be a good idea.
