Guidelines for Media Attachment
To ensure that your media elements are optimally displayed across all devices and platforms, please follow these guidelines:
Pictures
There is no size limit imposed on image attachments. However, note that the image attached is displayed on mobile devices and is reloaded each time a user refreshes a job.
Recommended settings for cover images:
Use square aspect ratio.
When using a logo, make sure that the background is white.
Videos
Recommended settings to upload a video:
Use mp4 format.
The file size must be less than 30MB.
For best results, make sure that the video is 680x480px (480p).
Use a standard aspect ratio of 4:3.
