Sometimes, photos stay up for a few days, then disappear. I found it & posted it again: (looks like a ship at sea; it's a tear in a soifa)
Tony, if you hotlink a photo from another website, it is subject to the whims of that website. If the website moves or deletes the picture then the link is broken. It's better to upload an image directly to SoC; then it's here for all eternity.
Well, first it has to be on your machine (laptop, phone, whatever), so you might need to download the image first. Then you can either drag and drop it into a reply box on SoC or use "upload a file" under More Options below. **Edited to make correction. Sorry. (The picture icon is for a link to an online image.)
