copy photos from desktop file to a DVD r disk

after downloading photos from a disk ( phoots I took my self), I attempted to
down load to a new disk (DVD-R) by doign the following 1) right click on
file or photo, 2) going down and selecting "send to" and then CD drive "e" (
the only drive I have), 3) then a small box pops up with the first photo on
the file and says " Windows encountered az problem whne tryignt o copy this
file. What do you want windows to do?" ( there the details fo the photo
name, date camera tyep -JPEG and size) and two boxes saying retry or
cancel 4) there is anther box in the back ground that says "coping..."
and shows paper going from one file to anther.

What am I doing wrong?? This is the way I copied files before I think.
The only thing I can think I may have done wrong before is I used the drag
method to get these photos from one file to anther.
Thank you in advance.
