“On the Write page, go down underneath the area for writing, and you find the photo upload area.

Beside the file  area is  a Browse button. (Do not use the one in the blue bar at this point).  Click and go to the documents on your computer where you store your photos. (They should be saved for the web at 72 dpi and no more than 400 pixels wide)

Then upload the image by using the upload button underneath it, not the one in the blue bar.

When you are ready to publish them on the page, make sure that you click on “full size” so I don’t get thumbnails.

Make sure “link to file” is clicked. 

 You get 50MB of storage for free.”

Thanks again, Shewolf!
