KeyError: 'imaging_properties' configuring carousel tile

[Estevangomez]

Hi, I'm using plone 5.1 and installed collective.cover but when inserting images in the Carousel the image gets blurred
the images loses resolution independent of size, how can I fix it ???
and also clicking on the carousel settings icon appears only one blank line nothing more like the image below:

It's a good practice to put a traceback of the error you got in the reported issue.

For example, creating a Plone 5.1.1 instance with collective.cover (1.7b2), when clicking on settings of the carousel tile you get:

The same error happens in Plone 5.0.x. Isn't it related to https://docs.plone.org/manage/upgrading/version_specific_migration/p4x_to_p5x_upgrade.html#deprecation-of-portal-properties-xml? In Plone 5 we don't have portal_properties being used for this configuration. The functionality problem here is the same as #667 ("Can't configure tile in Plone 5") but with another fix.

For the "blurred" image, if possible, give us a print of the before/after or even attach the image here.

@Estevangomez we have more Plone 5 issues in #642. Are you familiar with Plone development? We can really get a hand for fixing these issues.

[hvelarde]

thanks for reporting the issue; this package is NOT compatible with Plone 5, that's pretty clear in the documentation.

[rodfersou]

IIRC there is a vocabulary to get the image sizes, what can make this template work in both versions of plone.
