Dear xman,
In this case you need:
1 In service "file upload" link - "fileurl" response parameter to some LSV.(for example "fileUrl").
2 Use following JS code to set this file asset to image component on event and page you need:
pre
//Note: you need use here LSV from 1st step.
var fileAsset = localStorage.getItem("fileUrl");
Appery("picElementName").attr("src", fileAsset);
/pre
That's all.
Regards.
