Multiplied image to png
Here is one thing you can do.
Copy the image you want to multiply. (CtrlA and CtrlC)
Make a new 'Black' color layer and click 'add mask'.
alt-click the Mask icon, so that you can enter to mask edit mode.
Paste your 'multiply' images in the mask (b/w) , and then invert it.
You will have a black layer with your multiply material masked.
You can adjust opacity of that layer to find best looking image. (30~40%?)
If you save it as transparent PNG file, you are done.

Attaches a function called "seed" to Mongoose models, which basically wraps the create function, but returns a promise. This way seeding can be done through a promise chain.
var mongoose = require('mongoose');
mongoose.Model.seed = function(entities) {
var promise = new mongoose.Promise;
this.create(entities, function(err) {
if(err) { promise.reject(err); }
else { promise.resolve(); }
});
return promise;
};
