I have not successfully added a photo to a post - I've tried and failed : (
I have a blueprint drawing that I'd love to get some feedback on, do I upload the photo to my favorites under misc. and then compose a new message and check "add photo"?
I'm testing this message by adding a photo from my account.
Thank you for your help!
upload photo---> compose message---> click on insert photo(s) ---> choose photo ---> click on arrow to insert photo! Done!
And you can always provide a link.
