Media Attachments

The Social Composer includes a Media Attachments section for adding images, videos, or GIFs to the current post when those media types are supported by the selected social platform and content type.

Opening the Media Library

The Media Attachments area includes a Media Library button. When no media has been selected, the Composer also presents the media area as a clickable location for browsing your library.

1. Open Publish.
2. Select the intended channels.
3. Locate Media Attachments.
4. Select Media Library or click the empty attachment area.
5. Choose an eligible media asset.
6. Return to the Composer with the selected attachment.

Supported Media Depends on the Platform

Not every social network accepts the same media. The backend validates media URLs and platform/content-type combinations before publishing.

Examples of Platform Requirements

• Instagram Reels require video.
• Instagram Stories use vertical 9:16 presentation expectations.
• Facebook Stories also use vertical 9:16 presentation.
• LinkedIn images are generally expected in supported JPG or PNG formats, while video publishing has its own format requirements.
• YouTube publishing requires video media.
• X / Twitter supports images or video with provider-specific quantity restrictions.
• Threads supports text, images, and video.

YouTube Video-Only Validation

The publishing service explicitly rejects non-video media for YouTube. Standard YouTube videos and Shorts must use a supported video file. Shorts are expected to be vertical and short-form according to the platform requirements represented in the source.

Media Validation Warnings

AIUNIFY Social Media can return warnings or errors when the file type, URL, aspect ratio, or selected content type does not match the destination platform's requirements.

Changing Attachments

Review the selected media before publishing. If the wrong asset was selected, remove it from the current Composer selection and choose the correct item from the Media Library. Removing it from the Composer does not automatically delete the underlying asset from the Media Library.

Preview the Final Post

After adding media, review Channel Preview. The interface notes that the preview is based on the selected profile and that final appearance may vary by platform.
