At it's simplest, BlendGif will combine several single-frame GIF files into a new, animated GIF file.
But that's just the beginning ....
Would you like to view a detailed description of BlendGIF options?
The default options (set above) are used when you do not explicitliy enable image-pair specific options. For example: assuming you've specified 4 images: you could specify image-pair specific options for frames between the 2nd and 3rd images; and use the defaults for frames between the 1st and 2nd and between the 3rd and 4th image-pairs.

If you leave an entry blank, the server-files or URLs (selected at the top of the form) will be used
The basic logic used in these image-specific transformations is:
To do this, use a space delimited list of values for the parameter(s) that will be changed. For example, a move-right value of:10 50 90 100 150 would cause a set of (#FRAMES) frames that show the image moving right across the screen.
BlendGIF will match the relative frame number to the graph sketched by the values listed in a parameter. With creative specification, this gives a lot of flexibilty (i.e.; stop and reverse, speedups, slowdowns, etc.)
