I've enabled the attachment feature. Click Attachments and other options below your post to try it out.
• File types: jpg, gif, png
• Up to 1 MB each
• 8 attachments per post
The image displays below your post. If your image is too big, it becomes a thumbnail 600px wide. Click to expand. You can also click the link to download. (See the example below.)
Note that you can drag a file to that box to upload.
Feel free to use this for whatever. It might be especially useful for people wanting to post their photography. Or just as a convenience if you'd rather not upload an image to an image host. Also, externally-hosted images in general are prone to disappear after a while. We'd have no reason to delete attachments from our FTP, so they will definitely stick around.
