I published a project in the HTML5 format without converting my sphericals to a cube format.  Yes, it took a long time to save it....but the finished folder was only 18 MB.  When I try to upload to my server though, the ftp client chokes on it....meaning it spins its wheels without ever starting the upload.  I use Ipix Interactive Studio to build my images and it gives me the option to convert my equis to either a "Cube Strip" or a "Quicktime Cubic Panorama."  Which of these should I choose?  Is it my failure to make this conversion that is causing the finished HTML5 folder not to upload to the server?

Thanks,  Reggie
