Yes, I was using the HTML/Text Module to add the media. (I thought it used the functions of the media manager, but I was wrong.)

As I said, the files were in the directory. I checked via ftp. The files were listed in the pick/choose box when you used the html/text module to embed, but the images were white and when they embedded I got that error message. But only "some" of the images in the directory were like that and not all.

I can't give you any more info because it is fixed now... synch files may have fixed it.

Best,

Katherine
