#target indesign
#targetengine "MyEngine"
var doc=app.activeDocument;
if(doc.selection.length>0)
                    if(doc.selection[0].constructor.name=="Image")
                           jpgpath=new File(app.selection[0].itemLink.filePath);
                           bt = new BridgeTalk;
                           bt.target = "photoshop";
                           bt.type = "iterator";
                           bt.body="{app.open(jpgpath);}";
                           bt.onResult = function(resObj) {};
                           bt.send();
                           BridgeTalk.bringToFront("photoshop");

Answer 1

In your body script… jpgpath is just part of a string you have not constructed this to pass the variable… Also some classes are considered complex types so you need to toSource() and then eval…
#target indesign
#targetengine "MyEngine"
var doc=app.activeDocument;
if(doc.selection.length>0)
                    if(doc.selection[0].constructor.name=="Image")
                           jpgpath=new File(app.selection[0].itemLink.filePath).toSource();
                           bt = new BridgeTalk;
                           bt.target = "photoshop";
                           bt.type = "iterator";
                           bt.body = "{app.open( eval (" + jpgpath + ") );}";
                           //$.write( bt.body  );
                           bt.onResult = function(resObj) {};
                           bt.send();
                           BridgeTalk.bringToFront("photoshop");
