Unable to render image in base64 format with Picture widget on chrome and firefox browsers(Working fine in IE).
Issue analysis: I found that in order to avoid caching of images, base64 image string when rendered as URL , is appended with a timestamp(ex: base64_string+"?=timestamp"). Due to the presence of "?" a special character, entire base64 string is treated as invalid by the above mentioned browsers.
This timestamp attachment is happening @ line number 1324 of /updateImage function of Picture widget in file "freeboard/plugins/freeboard/freeboard.widget.js".#Freeboard.thingspace.io
