  Q. Size Limitations on Panoramic Image Download
           Asked by Mike Ombrello    (K=4878) on 12/10/2006
I have looked through the information within the Q&A but have not had any luck in finding the pixel and/or files size limitation for downloading panoramic images. Can someone point me in the right direction or provide me with this information. Thanks, Mike

"Hi, There is no limit on the pixel dimensions if the ratio of width to height is 2:1 or greater, although of course if you choose widths greater than about 1200 pixels people will have to scroll L&R to see the entire image. The file size limit is 400k, as with all other images. This means that you have to use fairly high JPEG compression. My experience is that for spherical panoramas (360 x 180 degrees, where width is exactly double height) 1,700 x 850 is about as large as you can go without unsightly compression artifacts. Your panorama is very wide and narrow, so it might be possible to get similar quality from an image 2000 pixels wide. Do let me know when you've uploaded a bigger image. By the way, be careful to uncheck the "use sharpening" options when you upload. Any sharpening should be done by you, at full screen resolution, before posting."
