You can only upload SWF files with a max size of 100 MBs. You can still use the internet option if your looper is larger than 100 MBs.
Please make sure that your looper is working correctly. Also make sure that we haven't archived your looper already. After your upload is complete
we will review your looper and post it to the site. If you run into any bugs or have questions, let us know on twitter.
