FileForums - SWF File upload..

I 'think' you used to be able to use image sites like PhotoBucket which support hotlinking. Not sure if they became stringent on the requirements though, IE. filesize. That would be what I'd look into. Most image sites class .swf's as images, so depending on your particular .swf, you might be able to get away with using one of those.

The alternative is to use some other file upload service which supports hotlinking. And this is basically none for free. Generally, you are looking at paying some sort of fee to be able to get this as one of the premium features. Or, get your own webspace and do it that way. Depends on your needs and what, if anything, you have available to spend.
