See the following screenshot from Google Chrome:
I was downloading the following:
- http://mis.haifa.ac.il/~ishimshoni/SegmentCrypt/Download.htm - the database from DropBox ("Images.zip" - no time given)
- http://research.microsoft.com/en-us/projects/objectclassrecognition/ - "pixel-wise labelled image database v1" and "Pixel-wise labelled image database v2"
Why do I sometimes get the information how long a download takes and sometimes not?
