Two extra comments after sleeping over it:

- is it really needed to ask for the blob file name? We
 could simply use the same file name as the source,
 but with modified extension.

- I think we should add support for multiple fit images
 at once, which is not hard to do. The user would
 specify a space separated list of its files.

Best regards,
