The trick to posting a full-size image in the body of your post is to use the Insert Image function. It is accessed by clicking on the itty-bitty square in the top section of the message composition/reply window that looks like a couple of mountains with the sun above. Doing so opens a small window where you can insert the internet link to your photo. The Insert Image function works only for photos from an internet source. You cannot use it to insert photos directly from your computer or phone.
To insert photos from your computer or phone, an additional step is necessary. Either post your photo to an internet website, or use the Forum to provide your photo with an internet link (that's what I do). To do this:
1. Click on the "Attachments" function (the paper clip icon in the message window).
2. Select your photo from your computer or phone.
3. Upload it to the Forum.
4. Use "Preview Post" to see how your post will look. Your photo will appear as a small image at the bottom of your post.
5. Click on the photo image. It will expand in a new window. Highlight and copy the web address from the address bar of that window.
6. Go back to your message composition/reply window. Click on the little "Insert Image" box (the one with the mountains). Paste the copied web address into the box that opens, and click OK.
7. Go back to Preview Post to make sure your image appears as desired.
It seems complicated, but once you've done it a couple of times, it becomes easy. Below, I did that with one of my photos, an "artistic"
shot from London:
