Indeed I highly recommend Dropbox or a file sharing site with a longer upload time limit. Grab the URL and everything works like a charm. Haven't done this in a while but I do remember it took me a second to find the upload via URL option. I'm usually slow with these things mind you.
Kyatric: Anything other than a blank error page is good How about go the extra mile and make the error page go into detail about what's going on:
"Our upload time limit is set to 2minutes maximum. If your connection isn't fast enough for this then no problem - click HERE to use our handy "upload via URL" option! You can use file sharing sites or Dropbox to generate a link and use it to upload content. Great!"
Quite informative and prevents topics like this
Thanks for the reply and have a good day!
