A hand-off service enables seamless sharing of session data of an online session between a server and a client with additional clients in an application, e.g., art application used for finding décor items. A user can request a server, using a first device, e.g., desktop, for access information for accessing the art application using a second device, e.g., smartphone. When the second device accesses the server using the access information, the server generates a unique storage address space that is connected to a session between the server and the first device. The user can upload a digital asset, e.g., image of a room captured using the smartphone, to the unique address and the server automatically renders the digital asset on the first device. The server can also render another digital asset, e.g., an art image, within the setting image.
