Description

portal/taxon/{uuid}/media service only delivers a filtered media object
which only contains the thumbnail representation even if the height and width filters are not set.

In cases where no filter is set this service should return all media.


old subject: portal/taxon/{uuid}/media returns only one media object even if no filter is set

This issue is due to problems in the algorithm implemented in MediaUtils.filterAndOrderMediaRepresentations(). The same problem has already been solved for the cdm-dataportal (#6683, #6969). The better algorithm from the portal code should be used also for the cdmlib.

This ticket (by description and by old title) is about handling the "no filter" case. Not sure if the new title still covers this. As far as I understand your comment you may only improve the image selection algorithm but if no filter is set not image selection has to take place.

But ofcourse I agree that we may additionally improve the image selection algorithm if there is a better one.

One of the problems is that "no filter" case is interpreted as a filter with preferred size = 0 and width = 0 which will always will return the thumbnail. So many aspects of the implementation are wrong that I refrain from mentioning all these problems only for the sake of transparency.
