Hello ... you can post photos in forum threads as a matter of routine – for example, if you need to illustrate your question with something that is difficult to describe. When you're writing your message, you'll see "More Options" underneath your message box, right next to "Post Reply" on the right. If you click that, you can upload a photo from your computer into your message. Quite convenient, although it does require space on Mr. Kellogg's server.
But in Conversations, there is no "More Options," so it doesn't appear that you can upload a photo. But you can post a photo in a Conversation if you have your photo somewhere else – in my case, I have a website, so I just upload a photo from my computer to a folder on my website (which no one can see: it's just a storage locker), and then I use an "Image tag" to include it in my Conversation post.
The tag looks like this –>
[i m g]<PHOTO URL>[/ i m g] – except that you remove the spaces I put into those two tags: I had to put the spaces in so they won't turn into real tags in this message. Then you put the URL of your image in between those tags; you know: the
http://(image internet address). That's all there is to it – except to click Post Reply when you're done.
The advantage of this for WordReference is that my bulky image file is hosted on my website and not on Mike's server, so it doesn't take up any room on his server for which he might have to pay more money for.
You don't have to have your own website, of course; you could use a photo hosting/sharing website, such as pbase or other – just any place on the Internet where you can upload a photo and obtain a URL to display it.
If some of that isn't understandable, let me know.
