Peggy,
I think the "tag line" for the pictures you are seeing is actually the file name it was assigned by whoever created it. The actual file name and size is automatically displayed in the bottom for the picture, no matter if you gave it a "Title" when you added it through the attachment manager or not. Did you actually give them a "Title" in attachment manager before you dragged them there???

No ideas of help on the video side of this conversation, sorry.
