Dear All,
The NHM, London is in the process of developing a web interface to its EMu specimen database and a query with relation to display order of multiple images has popped up. I would like to ask the EMu community on behalf of our web team whether any other institute has encountered this need and found an effective solution.
Let me give you an example. It may be the case that a Catalogue record has multiple multimedia attachments, and yet one is the preferred image (Default) to be displayed in list view. Alternatively we may have a series of images, perhaps a set of serial sections through a fossil, which we would wish to display in a set sequence.
Now it is possible for a user to re-order the images on the Multimedia Tab in the Catalogue to reflect the preferred order in which the images are to be displayed. I'm guessing that this has the effect of re-ordering the Multimedia IRN's in the link table...? Thus it could be possible for a web interface to contain a script that selects the IRN in the first row of the link table to display the 'Default' image for list view. Subsequent images to be displayed in detailed view would be displayed in the order reflected by rows 2 to 'x' in the link table.
I realise that this is not an ideal solution and open to errors. I was just wondering if any other institute had come up with a solution they could recommend? Is there a better way to manage this priority order? Is there a neat trick we're missing with the standard mulimedia set up? Or should we be adding a number of 'Priority' fields.....?
Thanks
