Hi, Sandy -
to get a link to your photos that everyone can see, go to the particular album on your facebook page, the page that shows all the photos from that album on one page. On the upper-left side, you'll find a gear-shaped icon. Click that icon, and then select "get link." The link that appears can be copied [CTRL-C] and then pasted [CTRL-V] into a Mudcat message.
Here's mine: https://www.facebook.com/media/set/?set=a.10152662838233260.1073741841.623958259&type=1&l=af88f45dab
