yeah this is how I do it.
from the quick reply in garage journel
open another tab in windows explorer and open photobucket to my album, locate the image i want to post in gj thread, under the image go to the direct link, high light and right click and then copy.
go back to gj thread in quick reply click on the insert image tab (7th tab from left)
delete the address shown and right click and paste the link from photo bucket

I still cannot post pictures from my computer.
