The way I figured is to start a free Photobucket (.com) account (I had one already).You upload your pics there,and before you post here,jump there (saving it to a favorites file makes it quick n easy),put your cursor just below the pic you want to post,the bottom "line" (can't remember what it's called),left click it,and it should say "copied to clipboard".then come here and start your post,when you decide where in the post you want it at,right click,see "paste" and left click it.While you are still posting,it will show as a url/link,but once finnished posting,it will show the pic.
This is much quicker and easier than I probably made it sound.This is how I posted this pic (a shameless plug to post me old Monocog 
).I hope this helps! 
ps:can you tell me how to get an avatar (I tried to upload one from my hardive and photobucket...nada,nothing) ?
Older and slower than I used to be,but every now and again faster than I ever was!
