Add a Full HD rendition on pictures and increase resolution of Small and Medium

When document type has the picture facet, preview should not the rely on the full resolution pic but on a smaller rendition.

Current medium view is too small (<= 500px) so we need to introduce a more appropriate view (ex: Full HD 1920x1080)

Small picture rendition width limit should be increased from 280 to 560.
Medium picture rendition width limit should be increased from 550 to 1000.
