Ah, uploading issues. I had a good deal of that a few days ago (music files).
Anyway, I recomend Rapidshare. Problem is, if you don't make an account (a free one), you are limited to 10 downloads and then it shuts off, so you are going to have to reupload it frequently. In addition, even if you have a free account, I don't know if the 10 downloads will be waived.
Mediafire works too, and may be a better option in the long run if you will add and do stuff to it. You have to log on at least once every month or two to keep them active, or have at least one download a month for the file. (If you create a free account to keep easy track of them)
There are also a few others out there as well if you search ''upload'' or ''upload files'' on Google.
Hope this helps.
