previews on material page - possible wrong file

[bianchini88]

In assets/materials/previews the two figures simovski_gsuite-hyperbrowser_2017.png and sandve_genomic-hyperBrowser_2013.png
appear to be the same (although the files are not identical). The actual content of the figure makes me think this should be used for sandve_genomic-hyperBrowser and not for simovski_gsuite-hyperbrowser.
