Reviewing what I have created so far on my new site design. In looking at the files in the files folder I'm noting multiple copies of the various link buttons I've created. Some marked are labeled IMG_# and some mo_IMG_#. This is also the case in some of the other images and bars which I have. It appears that I'm getting a copy every time I create a new page, though I usually copy the first page. Is this normal?

Yes this normal.

Then mo_IMG# is the 'mouseover' image.

Thanks.
