If the post you want to submit is just an image without a link, click the Submit an Image tab. If you can't see Submit an Image, it may be disabled by your Community Manager.
Click Choose File to select an image from your device. Then Add a Title in the box above your image. You can add an optional Description below.
You can also Add a Note that'll be displayed above the post. Use this to let the community managers and members know why the post is relevant. You may be able to select a category for your post (if allowed by your community managers). Select it from the dropdown.
Once you are finished, click Submit. Your post will need to be approved by a community manager before it will be available to view or share. You should receive an email with a link to your post once it has been approved.
