One solution that works well for me would be the following: Store the picture like you did in a nt:file node (of course). Then as the source for your img tag write something like

Then write a Servlet that returns the image (i.e. the content of the 'data' property). This Servlet would be mapped to the path /image/* in the web.xml like that:

ImageViewerServlet

/image/*

The Servlet itself just reads the path after '/image' (here: path/to/your/node), looks if it can find a corresponding node in the repository and (if yes) returns the binary data stored in the jcr:data property in that node. I attached a "BinaryViewerServlet" class that I wrote some time ago. It's not exactly what you need I think but it should be pretty close. I that class I expected the full path including the property, so ending up with '.../jcr:data', which is more generic. If you only want to do it for nt:file (or nt:resource), then it would be enough to have the path to the node and let the Servlet read the property. And: the Jackrabbit team did some nice things about how to retrieve sessions in web applications etc.. So ignore the way it is done here and look around, it should be part of the "Jackrabbit Web Application" component... ;-) Hope that helps a bit.
