This is the way I do it, but others may have a different or maybe even a better way.
I upload my photos to my Flickr account (some people use Photobucket and I think there is a way to upload pictures directly to the BYH site, but I don't know how to do that). When I want to put a photo in a post, I copy the URL of the photo (it will look something like this - http://farm9.staticflickr.com/8232/8575097116_80d7916b2c.jpg) and paste it between these brackets -
. When you submit your post the picture should appear.
Thanks for the insite on how to do this. I am frustrated as well trying to post. I read somewhere that you can post after 8 but now this says 10. I hope to find out soon.
