I would now like to associate several (hundreds) records to the same cover image.

(These are books belonging to an old collection, for which no ISBN exists and therefore no image is available on amazon, all sharing the same sort of cover jacket.)

Should I enter the same cover image for each record separately, this would result in an unnecessary increase in the size of the biblioimages table, and therefore of the whole database.

I wonder whether some sort of "aliasing" would be possible, in this case.

A related question is also whether adding a cover image to a record could be performed routinely through an external script, rather than through the Koha staff browser, to expedite the procedure in the case of several records.
