When you post click the button that says go advanced, page down a bit and on the left it says "manage attachments" click that select file and upload file, not hard.
I had problems getting mine to upload directly from my computer, so I had to load them onto Photobucket, then from there I had no problem getting them here, just when you 'go advanced', once you click 'manage attachments' just click either 'from computer' or 'website'
Good luck
They was having trouble about 2 days ago then yesterday it was uploading
right on check my journal. When you post you hit on the 3rd icon from
the right then click on select file when your done selecting you hit on upload
file. When it's working right you wanna have the pointer where you want the pic
to be at on the page then you can drag the pic around on the page too~
It Works!
