Lynnie:

To post pictures, you have to store them on-line somewhere. Photobucket is what I use and it's free. Once it's transferred there, copy the "direct link" listed for that picture. Click on the button that is next to the envelope in the posting form "enter an image". Paste the "direct link" from photobucket and you're done.

You need both pressure and volume to wash the pipe in, I think a sump pump with a garden hose attached might work. Sump pump could be put in the pond and run off of a generator if no electricity is close enough to the pond.

I'm sorta confused. Is the pond down near Bloomington?
