First you have to post the picture in the gallery.
If you are signed in (and you may have to sign in again) then you do like
you are going to make an original post or post a reply.
Down at the bottom is a line that says"[IMAGE LIBRARY (UPLOAD/SELECT)]"
next to a gray box that says "Image URL" Click on "Upload" and it will
guide you through. There is a maximum file size, I think about 60K so
you may have to edit your pic to get it small enough. On Kodak's Easy Share
(snicker) software there is an option under "Save as" in image size that will
give you an appropriate resolution and size for posting on the web.
I don't remember exactly what it is called but the word "web" appears in that
option.*
Once you get your pic in the gallery, go to the gallery and copy the
image source name the gallery has given to it and paste it into your
post where you want the pic to appear. After you've done it a few times
it comes fairly naturally.

*NOTE!! The above is NOT an endorsement of Kodak's "Easy Share" software!
It thinks it owns me and my computer both! Also takes up a lot of resources.
I kill the program every time I boot my computer unless I need it at the time.
I have removed it from my Start Menu numerous times and it keeps reinstalling
itself there and running in the background, bogging my computer down and trying
to take control whenever I insert a CD.
