There are two reasons for this:
1. In order to warp the images, The Panorama Factory must know the camera’s focal length ... in pixels (!). It computes this from the focal length in millimeters, the image size in millimeters (24mm x 36mm for 35mm film) and the image size in pixels. If the images were different sizes, we wouldn’t know which one to use in setting the focal length.
2. By requiring all images to be the same size, the software can be simpler. This in turn leads to more efficient and more robust software. |

Ad 1: Well, then, but what if the scanned images are not full-frame ones? I have some photos of my ancient self-made-prints era and I can't now determine what part of the original frame they represent. Besides, some of these hand-made panoramas have their "member-photos" cut to different sizes, according to the best-aligning features (though still overlapping a little) - should I now add "artificial" whites around the (scanned) smaller ones to get the even size?

Unfortunately, the answer to W. Paul's question is not a positive one. Some applications may be beyond the capabilities of The Panorama Factory. This may be one of them.
Adding white space around the images is unlikely to work well for several reasons.
1. The image warping required for panoramic stitching must be performed with respect to the central axis of the lens. The Panorama Factory assumes that the central axis of the lens projects onto the center of the image. The hand-cutting may make it difficult for you to achieve this requirement by adding white space.
2. If the white space is to the left or right of the image, it will probably confuse The Panorama Factory's automatic alignment code.
3. When the white space falls in the overlap region, The Panorama Factory will probably blend the overlap incorrecly. You may or may not be able to improve this by adjusting the boundaries of the blend region.
Good luck! |

Is there an easy way to get your images to get to the same size. I'm not off the ground with the product because no two images are the same size. |

Yes, there is a feature in The Panorama Factory designed to help you trim your images to a fixed size. The trimming feature is available through the Classic (menu-based) interface only, so you won't be able to use the Wizard. To learn about using the Classic interface, refer to Using the Classic interface, step by step.
The trimming feature is described at Trim the images. Two trimming methods are provided. The first, Trim marking corners is used when the edges of the image are visible within the scan (e.g. overscanned prints or negatives). The second method, Trim rectangle is used when the corners of the frames are not visible. You choose the trimming mode with the Trim menu.
