Provide the ability to generate a thumbnail image alongside the bursted image

[jadrake75]

Note Brought forward from Image Bursting 2.X backlog

When bursting the images to disk, it should be possible to indicate that a thumnail image should be generated. The thumbnail sizing should be configurable via an Options Panel and the image thumnail should be output based on these sizes.

Design Issues to address:
(1) Should the thumbnail always be a fixed user-determined size (eg. 200x320) using transparency (if available) to balance the image ratio
(2) Should the thumbnail be scaled such that it maintains its larger ratio, however the maximal size is dictated by the user option. (eg. given an image of 800x600 pixels and a thumnail of 200x320 pixels, the output size of the thumbnail would be 200x150 (since the width ratio of 4.0 exceeds the height ratio of 1.875)

Is the thumbnail something the user will print or only used for digital display?

[jadrake75]

Good question. If I used this personally, it would only be for digital display. It is unclear from the users/dealers who requested it which it would be. If they are selling on bidstart.com, ebay, etc. it would be display only. If they are producing an auction catalogue it could be print. I am not sure how many of the later we have as users.

Ok, given that the size is specified in pixels I would assume it was for display only, in which case the Exif would not be a concern. If the size was specified in physical units then the DPI of the full cropped image could be adjusted to make the printed image scaled down on paper.
