# Add images and video to a post

Upload media, check the preview, and choose a format that fits your destinations.

The selected destinations determine which media and options the composer offers. Choose those accounts before adding files.

## Add media

1. Open the [manual composer](/posts/create), choose destinations, and write your content.
2. Continue to **Media**.
3. Select **Click to upload media** and choose supported images or a video from your device.
4. Wait until the upload or generation finishes.
5. Inspect the preview and remove any file you don't want.

Use the file-type, size, and format guidance displayed in the composer. Requirements differ between channels. The [brand library](/brand/library) has its own image upload rules.

Use **Add Media** to attach more files when the selected destinations allow it. Use **Remove all** to clear the selection, or the remove control on a preview to remove one file.

## Generate an image

Write a caption or topic in **Content** first. In **Media**, select **Generate image with Moosen Autopilot Intelligence™**. Wait for the generated preview, then check it against the real product and your intended message. Remove it if you want to use your own photo instead.

## Match the format to the channel

Instagram image posts, carousels, Reels, and Stories use different options. YouTube requires video. Some destinations support several images; others require a different format.

Moosen can crop or size imagery for delivery. Review the preview so labels, faces, and important product details aren't lost.

## Keep the image accurate

Check any generated imagery against the real product. Pay attention to packaging, text, colors, and quantities. Use [Refine](/posts/refine) if an existing draft needs a different image.

Uploading a video doesn't turn an image-only post into a suitable video for every channel. Confirm the selected platform's media requirements and [publishing options](/channels/overview).
