Just a tip when you use a photobucket link. Just look in the drop down box on the pic in photobucket and look for the link that says IMG Code. Put your cursor on that, right click, choose copy.
Now come here to your post you are writing, place your cursor in the post here you want the pic to appear (I normally go after all of my typing) Right click again, choose Paste and the IMG Code link will show up. Thats all there is to it.
When you are done typing the post just click submit and you are done. You can always preview prior to see what it looks like. I find this easier than trying to upload pics onto the server.
