- Modified directory copy to not filter out files with size=0
RAZ-2955: Thumbs not showing for additional renditions for movies, videos or files
- Fixed serious bug for erroneously calling 'resizeimage' method on videos which leads to creating thumbs for every frame of video and eating up system resources
- Fixed to only show thumbs for images
