i use photobucket and just copy and paste the picture from the url under the picture you want and paste it into the place where you want to post it. like where you type. and it should pop up
I couldn't post any pictures either. I actually just opened a photobucket account today. Just upload your pictures on their and then paste the link in a message on here and people will be able to open it to look at that way. Kindof a long process but it worked very well for me!! Good luck!
or you can take the direct link to the image on facebook and then put it between [*img] and [/*img]
remove the * and then it'll show up on the site.
People are less likely to look if you post a link as it can take a while for them to load in the new window
