How do I make sure my images are posted as an inlined image rather than as a link on Twitter?
In order to have an image show up large & beautiful on your Twitter posts, you will need to attach that image to your post as seen in the video below:
1. Create your post.
2. Click "attach image"
3. Upload your image 2mb's max - jpg, png, or gif (gif files will be accepted, but show up as a static image).
4. Make sure the image is below 3MB as this is the limit for Twitter.
By using images with 2:1 aspect ratio, and vertically centered graphics and text you can optimize the in-stream preview.
