Use Codex’s Image Gen skill to create images from a description or edit attached references. Mains can show the result in the conversation and in Atlas. The skill must be available and enabled in your Codex runtime. A separately installed marketplace plugin is not always required; use the capability shown in your installed skills list.

​
Create from Atlas

1

Open New image

Open Atlas and choose New image.
2

Describe the image

Write a brief or choose a template such as Poster, Illustration, Product photo, Icon, or Infographic.
3

Add a reference

Attach, paste, or drop an image when you want an edit or a result guided by an existing visual.
4

Send and review

Mains starts a Codex Work conversation with the Image Gen skill. Continue in that chat to ask for changes.
If the skill is missing or disabled, the image workspace gives setup guidance and a refresh action. It does not silently start an ordinary text task.

​
Create in a chat

Select Image Gen from the skill menu and give a visual brief:
For an edit, attach the source image and describe the specific changes. Generated images open in a preview when clicked.

​
Keep the original

Download the original image or choose Save to Atlas. Seeing it in Atlas’s generated view does not create a permanent copy until you save it. The saved Atlas copy survives deleting the conversation. See Atlas for ownership and saving behavior.
