While we are still working on fully supporting the ability to include embedded images (hosted at pic.twitter.com) in your tweets, we have made a work-around easier to use.
Now, if you paste an image url that is hosted at “pic.twitter.com”, CTT will ignore the link and not attempt to wrap it in our URL shortener (which prevents it from displaying properly on Twitter).
For now, if you want to embed images in your CTT links, you’ll need to upload your image using your normal Twitter client (or the Twitter website) and tweet the image. Then, you can copy and paste the link to that image (starts with pic.twitter.com) into your CTT.
We are also now ignoring any bit.ly links and not wrapping them in our own URL shortener.
If you have any questions about these changes, feel free to contact support.
