Preloadr.com - Enhance Quality of Flickr Photos

I like this site - simple, straightforward and clean. Preloadr.com cleans up photos that you want to upload to Flickr. All you have to do is use this site before sending the images to Flickr (this site is designed to pre-process photos, not post-process) and they will help you enhance the photos with several tools like cropping, sharpening, color correction and much more. Once you've optimized your photo you can set tags and write details like you do on Flickr. If you're a Flickr Pro user, you can edit an existing image and replace the current copy with the new version. The whole site is that simple and easy. The question is: is that enough for any website these days?

Preloadr is a free service providing image manipulation functions linked with your Flickr account. It is designed to pre-process photos uploaded to Flickr. Based on the unique technology of nexImage and the public API of Flickr, this platform connects to your Flickr account and brings powerful image manipulation tools right to your browser. No special installation and no additional registration is needed. Our main goal ...is to extend the fantastic capabilities of the Flickr platform with state-of-the-art image editing functions and make all that accessible from any computer connected to the internet. You can use this service to enhance your photos before sharing them with your friends.

Flickr is the most popular photo hosting site on the internet. Any tool to enhance the quality of the photos on this site is a killer. I especially appreciated the focus of the site to do one thing really well and to stick with that use.

How are they marketing this tool, as they are not getting high traffic volumes? Is this tool officially supported by Flickr? How are they making a profit? Is there a reason they are not linked to other photo hosting sites, as there are many out there and everyone wants to optimize their photos. Why is this a pre-process technology?
