This works, only the IP without the SCI and VIS

mqttClient.publish(&In[0], "@im8 IP:"https://i.imgur.com/vFexxxx.png"\r\n");

Solved
Thanks

Thanks for the Tip, but it not update the graphic.
What make i wrong?

loop()

   unsigned long currentTime = millis();
  if (currentTime - previousTime >= eventInterval) {   // every 20 seconds
      previousTime = currentTime;    
      s_quality = modem.getSignalQuality();
     
     if (oneTime == 0) {   // it load the graphic

mqttClient.publish(&In[0], "|IM UID:im8 X:10 Y:45 W:12 H:12 OPA:1 SCI:0 SCM:2 VIS:1 IP:"https://i.imgur.com/GGxxxxx.png"\r\n");
oneTime = 1; // load the graphic only one time and it works
}

    if (s_quality >= 24) {
     mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:\"https://i.imgur.com/8dxxxxx.png\"\r\n");  // but don't update! The graphic exists
     Serial.println("Signal Top +");                                                       
    }
    else if ((s_quality >=20) && (s_quality <= 23)) {   

mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:"https://i.imgur.com/2dxx3xx.png"\r\n"); // but don't update! The graphic exists
Serial.println("Signal Good");
}
else if ((s_quality >=16) && (s_quality <= 19)) {
mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:"https://i.imgur.com/TJxxxxx.png"\r\n"); // but don't update! The graphic exists
Serial.println("poor signal");
}
}

Best regards

@im8 IP:"<image>"\r\n

BR,

Perhaps one way to solve this would be if it were possible to assign a variable to IM UID:var

Best regards
