I want the option of choosing between qtvr and flash, now when i export "image file only" from panoramafactory everything over the centerline curves down and everything under curves up.
is there any way to fix this?
This does not look good when its inserted into flash pano.

The curvature you are see is an unavoidable consequence of the spherical (equirectangular) geometry required for stitching extreme wide angle panoramas. It's not possible to create an image wider than about 120 degrees without this curvature. You'd need an infinitely long image file to present a 180 degree image with conventional perspective!

This subject is covered in more detail in the FAQ section on Panoramic image "distortion".

Many panoramic image viewers (e.g. QuickTime, PTViewer) remap the image so that it has conventional perspective when displayed on the screen. The viewers can do this because they present only a section of the image, usually less than 100 degrees.

On the other hand, some other viewers do not perform this remapping. Instead, they just crop a section of the image for display on the screen. This is similar to using the Windows horizontal scroll bar to show a section of the iamge file in a browser window or, indeed, in The Panorama Factory itself. When you view an image this way, you still see the characteristic curvature of the iamge.

I'm not familiar with panoramic viewers written in Flash, so I do not know whether any Flash viewers are available that perform the remapping from spherical geometry to conventional perspective.
