You'll be very welcome here Susan.
If you want to add a picture yourself..It's very easy.. Click on the icon in this header bar.. the one that looks like a frame (hover over it and it will say insert image) and click on it.
Then.. select: From Computer, choose file... then: Upload file.. and it will come up with a lot of gobbledegook in amongst [attach] and then it will be inserted in the post.
I hope that's clear .. if not, just should and someone will help you.
