how to embed image in a share value node

In a software I developed with Vuo, actually I read an image from external files. The drawback is that if I move the composition to another mac, I must remember to move the image file as well.
My idea is to put the RGB data into a “share value” node, in order to fire it at start and then pass it to a “interpret data as image” node to get the image. With this method, the image would be embedded into the composition, without external dependencies.
In practice, I cannot paste the RGB values into a “share value” node, so I am stuck here.
Any idea?

Follow-up. The correct way to obtain my goal is to use “Fetch image” node with URI format as described here.
