The TBhp upload control must be compressing the image quite a bit and thereby loosing out on the clarity and sharpness by a bit. Its a necessary evil to save disk space! |
Flickr preserves the original image that you upload as is. But it then makes smaller resolution copies of it to display the large/medium /small sized versions and in that it does some amount of sharpening in the smaller sized versions for a better display of them. It does not change any colors nor will change saturation.
Tbhp server does an aggressive jpeg image compression thus resulting in jpeg artifacts along the sharper edges in the image.
Here TG's problem is entirely different and I think it has got to do with the colorspace information, whether it is preserved or not while compressing the images at tbhp server. Have a look at both his images, the difference in colors is very evident.
EDIT: My colorspace-unaware IE 6.0 display both images in the same colors. But the browser that I use (latest FireFox) which is now colorspace-aware, displays both images in different colors.
