Azure Storage Explorer or portal view do not currently allow previewing of images with thumbnails. There are some third-party tools that supposedly allow previewing or thumbnails. Please note that I cannot endorse these or verify their security and I am providing these as a courtesy. Please do your own due diligence when researching software.
