The actual images were created by using Google Picasa to export them in the varying sizes and then they all were uploaded at the huge size so KAS did not do any shrinking. The others (browser resize) all that the 900 by 600 image and use the browser to resize the image.
Conclusion: (Do you agree??)
1) Sadly (in IE 7 not Firefox 3) I can tell a significant degradation of the browser resize photos that I think may rule out us using it unless we can verify that is what the other sites are doing. Look at the middle of the red lines in the "C" of Congratulations. Also look at the red and blue stars on the white table cloth, they are not as sharp in the browser resize photos
2) The browser resize works worst in the smallest two sizes (even in Firefox 3)
