Sending large files can be a pain in the *** sometimes. Most webmail programs have a limit on filesizes and using IM isn't very efficient. A good solution is to use YouSwap which allows you to share up to 1GB of files.
To send files all you have to do is type in the email addresses of people you want to share files with and then upload them. You can share as many files as you want, but they cannot exceed 1GB in total. Files are stored for 14 days which should be more than enough time.
