For me, the image links aren't working (yeah, probably because of dropbox), probably because following the link, I have to download the image to see it on the page. Probably just posting the image somewhere other than dropbox would be better for showing the images on forums. Also, if you hit the reply button here you can attach the image right to your post and don't have to upload it anywhere else, I assume that hosts the image on the ZFGC servers or something. I actually have no idea how it works :p
