I will try to figure out why I can't post [b]photos with comments here.
Think of it like this: Post [b]Comments with Photos
While you're in the composing window, after you upload your photos, go back and click on "Manage attachments" and a drop down list will show what you've uploaded successfully. Click on the Green mini icon in that list to "Pin" the photo to your post. Then, ensure there is a space between and you can add comments either beside, or after the photo...
(Clear as mud?)
