<div>The thumbnail needs to be PNG and <b><u>139</u></b>x109 (not 159x109). I’d also double check the spelling and casing of the directory in TFTP;

<p class="MsoNormal">Not sure if anyone is still using on-prem CUCM much these days but am trying to update some 8811 background and am getting a “Wallpaper cannot be set. Incompatible image size”.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My image and thumbnail are:<o:p></o:p></p>
<p class="MsoNormal">800 x 480 x 24 bit<o:p></o:p></p>
<p class="MsoNormal">Thumbnails are: 159 x 109 x 24 which match the existing backgrounds.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Although there is some documentation that says they need to be 139 x 109 for the Thumbnails.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would have thought the original included images would be okay? But they are not displaying either.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone done this and know for certain what they should be?<o:p></o:p></p>
