I have a dynamic content on one page that I want others to be able to change.  After I create the page, then preview, the page shows the dotted border as it is supposed to.  I can enter text anywhere and save it, and it works fine.  However; when I bring in an image, it looks good in the editor, but as soon as I save it, the image disappears.  Ehen I press "save", a green bar seems to go across the bottom as if it is saving, but then the screen goes to a blank.  I have waited over an hour to see if it is timing or something, but the image never gets saved.  If I press preview, only the previously saved text shows.  What am I doing wrong?  No error message comes up at all.

Thanks
