Playground Image Support: Issues with Empty Messages Explained

Does the playground support images? When I try to open a trace with text and images into the playground, the messages that contain images appear empty.

The Phoenix Playground does support images, but there are some limitations. According to Phoenix's documentation, images can be included in LLM traces using either a base64 UTF-8 encoded image or an image URL. However, there have been issues reported where images expressed with data URLs do not display correctly in the UI, as noted in a GitHub issue. This issue might cause the images to appear empty in the playground.Would you like more details on how to properly configure images for use in the Phoenix Playground?Sources: - Phoenix's documentation - GitHub issue
