Answer 1

You can use the below code which is in one of the examples in the demo folder of jointjs npm package.
joint.shapes.devs.MyImageModel = joint.shapes.devs.Model.extend({
markup: '<g class="rotatable"><g class="scalable"><rect class="body"/></g><image/><text class="label"/><g class="inPorts"/><g class="outPorts"/></g>',
defaults: joint.util.deepSupplement({
type: 'devs.MyImageModel',
size: { width: 70, height: 50 },
attrs: {
'.port-body': {
r: 5,
magnet: true,
stroke: '#000000'
},
// rect: { stroke: '#d1d1d1', fill: { type: 'linearGradient', stops: [{offset: '0%', color: 'white'}, {offset: '50%', color: '#d1d1d1'}], attrs: { x1: '0%', y1: '0%', x2: '0%', y2: '100%' } } },
// circle: { stroke: 'gray' },
'.inPorts circle': { fill: '' },
'.outPorts circle': { fill: '' },
image: { 'xlink:href': '/images/rout6.gif', width: 70, height: 50, 'ref-x': .5, 'ref-y': .5, ref: 'rect', 'x-alignment': 'middle', 'y-alignment': 'middle' }
}
}, joint.shapes.devs.Model.prototype.defaults)
});
joint.shapes.devs.MyImageModelView = joint.shapes.devs.ModelView;
// Usage:
var imageModel = new joint.shapes.devs.MyImageModel({
position: { x: 10, y: 190 },
size: { width: 70, height: 50 },
inPorts: [''],
outPorts: ['']
});
stencilGraph.addCell(imageModel);
