Mike, the way I've always done it is to start an account with someplace like Photobucket or another similar site and download them there first. First I downsize it and then download it to Photobucket, once it's there, then click on the particular photo you want to download here and on the right side of the pic you'll see a box labeled " Links to share this photo" click on the one line on the bottom that says IMG, (left click on the box next to the IMG). It will say copied and turn yellow.
Then go to this site and type in your posting, pick where you want the pic to be in the text with the cursor and right click there and then left click on paste. Type more text if you want and another pic later, if that's what you want.
You can preview the posting before it's actually posted to see if it looks the way you want it.
Remember if you move the photo to another file or close it at Photobucket, the photo you posted here will be lost on this site, but not at Photobucket.
I like doing it that way because it doesn't take up any space on this web site, and the photo here is larger and sometimes it's clearer to see the details.
Like this,
