Click "Settings" → "Spatial Data" at the top right of the point space → There is an option to add icons in the toolbar above the signature file box below → Save.

Then when you leave a message in someone else's space, check "Use signature file" below after editing the message content, so that the pictures in the signature file will be displayed below your message content.

If the picture option is not inserted in the edit box of your QQ space signature file, it may be because the QQ number was monitored by the system or reported by many netizens because it posted information that violated the Internet security standards, so this function operation is not supported at present. Please protect this number from being violated on Tencent's related platforms, and please check whether there are any bad information in the space (such as logs or pictures that failed the audit).

Tip: If you don't operate it yourself, it may be caused by the password being stolen. Please carry out a comprehensive antivirus on the computer, and then change the password as soon as possible.

Then you must update and enrich your space content in the near future (publishing/reprinting logs, uploading photos, publishing and talking, etc. ), and this function can return to normal after a period of time.
