Okay, STEAK
I see what you're doing.
You're clicking the INSERT IMAGE icon and then Pasting in the link to your photobucket image
That won't work (obviously)
You need to Open the pic at photobucket all the way
COPY the Image Code
PASTE it into the Reply Box
Ignore the Insert Image icon entirely. That's for when you're inserting an image off a non-photobucket webpage
