zooomr and flickr part 2

In my pre­vi­ous post on zooomr, I men­tioned there was a dif­fer­ence in the level of com­pres­sion used by flickr and zooomr. I now know that is not the case, the dif­fer­ence is that if you upload a stand­ard size (ie 1024px x 768px) to flickr, flickr will not repro­cessed the image and will use the image as you uploaded it. So if you uploaded a 200k image at 1024px x 768px, the image avail­able at the large size will be 200k.

Zooomr on the other hand does repro­cess the photo, so if you upload a 200k image at 1024px x 768px, the image avail­able at the large size will prob­ably be around 600k and because it has gone through another round of com­pres­sion it will be of lesser quality.

Note I have yet to see what hap­pens if I upload a high quail­ity image to flickr, say a 1Mb 1024px by 768px and see if that is reprocessed.
