In pageproperties there is a thumbnail field available where user can use upload or select from dam.
If I upload it will be saved as /image/file/thumbnail/thumbnail_315
If I use select it can be used as /image/filereference in the HTML or jsp
In the same way how can I access the image of I save it using upload as it is store as in the following node structure
Also does the image uploaded using the upload option will rewrite the name of the asset as it is saved s thumbnail_315
