This forum allows for the inclusion of images, like this one
right in-line with your post. Click on the camera icon below, insert your image & then use the blue-dot grab handles to re-size.
You can also include video with the video camera icon, attach files with the "upload" icon, add dividers with the odd "line-in-rectangle" icon
and code snippets with the >_ icon. GIFS are also possible, as are emojis.
What though, you say about URLs? All you need to do is "select" the text you want to link to a URL, and then an option for adding a link will appear. Please do use that functionality rather than including long URLs in these posts.
