This IBM Worklight Information Center article mentions that:
The thumbnail image provides a graphical identification for the application. It must be a square image, preferably of size 128 by 128 pixels. It is used to identify the app in the IBM Worklight catalog.
IBM Worklight Studio creates a default thumbnail image on creating the app. Override this default image with an image that matches your application. The file is in the /common/images folder of the app.
I have tried to replace with the default image with my image under common/images/thumbnail.png.
In application-descriptor.xml:
<thumbnailImage>common/images/thumbnail.png</thumbnailImage>
However, the thumbnail displayed in Worklight Console remains unchanged.
May I know if the setting <thumbnailImage> in application-descriptor.xml equal to the thumbnail displayed in IBM Worklight catalog as mentioned in the Information Center?

May I know if the setting in application-descriptor.xml equal to the thumbnail displayed in IBM Worklight catalog as mentioned Information Center?
Yes. The thumbnailImage element in application-descriptor.xml allows for changing the thumbnail image displayed in Worklight Console, as mentioned in the IBM Worklight Information Center article you have linked to.
This is a defect in Worklight Console.
Will be fixed.
Thanks.
