I am not sure of the nature of the problem you have with posting pics.
Is it that you can only view pics one at a time on your laptop or that you can only select one at a time?, Ctrl click will select individual pics to batch drag.
I have settled on a method which works for me by creating a desktop folder called post pics and using (free) FastStone Photo Resizer to resize to 800x600 and sending them there I can select all and drag to post. The originals are still left where they were. After posting I empty the folder ready for next time. You probably know all this already so dont be offended by my comments and you do good video.
