Hey! I have a question about JS-IPFS. Let's say I want to display a gallery of images on a webpage, and those images are on IPFS. Stuff on IPFS takes a *long* time to discover / fetch, so I'd like to spawn a local node using `js-ipfs` to help.

Right now, I'm doing something like this : 
```javascript
gallery.ipfs.on("ready", () => {
    fetch("./json/gallery.json").then(response => response.json()).then(json => {
        json.galleries.forEach(element => {
            console.log("ipfs pin add " + element.base32);
            gallery.ipfs.pin.add(element.base32, function (err, res) {
                console.log(err, res);
            });
        });
    });
});
```
Is it appropriate to call `ipfs.pin.add` like that? Is that really helping?
What should I do if I want to use the spawn node efficiently?
