Are you using the URL from the museabuse website? Because I don't think it'll work from there. The only way I can get it to work is by copying it on my computer and uploading it to photobucket and then getting the url from there. Seems like a lot of work, but that's the only way I can get it to work. And, yeah, I upload it on this website the same way I do pictures.

Hope that helps:)
