Once your photos are on a photo hosting site (such as Imgur.com; Postimage; Dropbox, etc. Photobucket), or on virtually any site, including this site's album such as eBay; Amazon Pinterest; Facebook; an online Pipe retailer; you-name-it, select the full sized image, then Control-click (Mac) or Right-click (Windows) on the image itself, then choose "copy image location" or similar words. Now paste that URL (the full web address, which should end in .jpg or .png) into the IMG box in the reply window of the thread you're posting to.
The site's album is also a good choice for displaying photos, and the same method works for obtaining the image's URL for copying into the IMG box.
There are other good illustrations and steps on how to post photos under "Latest Discussions" in different formats:
This is how to add photos to your post using the site's photo album:
Here ya go!
Images tend to be smaller than hosting site's size, but can be full sized if you remove the pixel limitation, (-600x360)— the numbers and the dash preceding, leaving no spaces, and ending in .jpg
An example, of a thumbnail named "hms-penzance-1940...." followed by "-150x100.jpg" is the name of the photo in my album, and it's the "-150x100" that limits the size.
If I remove the numbers, it goes to whatever size at which it was uploaded, subject to web sized image limitations.
Dbl post. Pardon!
I am a firm believer in the people. If given the truth, they can be depended upon to meet any national crisis. The great point is to bring them the real facts, and beer.

If it's on your computer, you drag it into the image box (see below) after opening the dialogue box. If you want to LINK*to an image, click on the link button and paste the URL into the box that opens. The symbol to LINK is the right hand symbol on the upper left of the box. (Looks like a tilted infinity sign.)
No need to resize, as the server will do that for you. Choose full size image, not thumbnail.
* Photos from many—even most—websites can be displayed by copying the image's URL, usually by Control-clicking onna Mac; or right-clicking on Windows, selecting the URL (often stated as "Copy Image Location" or similar words), then copy/paste that into the window.
