The TMF doesn't have space to which things can be uploaded to share. So, if you want to share something, you'll need to find space where you can upload your goodies and then hotlink to them in your posts. Unfortunately, there are very few free spaces that allow hotlinking because of the bandwidth costs. But, there are a number of membership places that aren't too bad in price. Of course, if you just have a few images and wouldn't have use for it enough to pay for space, you could always ask if someone who has space is willing to host them for you.
