Hi Bill, welcome to WeDig!
There are a couple options for posting pictures. The simplest is attaching them in the "Attachments" section that shows up just below the box where you type in the post. Here's a link with a step-by-step
The pictures themselves won't show up on the page, just a link (that trick's reserved for lucky admins -- I wish they'd fix that). But folks who read your post will be able to simply click the attachment link to see the picture(s).
If you have any trouble, always feel free to e-mail me directly at firstname.lastname@example.org
. You're welcome to send pics to me and I'll upload them, with captions, for you.
