'How to open the newly created image in a new tab?
Below code creates the image in the bottom of the same page. How to display that image into a new tab/window instead of displaying in the same page?
success: function (data) {
var image = new Image();
image.src = "data:image/jpg;base64," + data.d;
document.body.appendChild(image);
}

Current suggestions were not working on chrome, I was always getting a white page, now I am using
const base64ImageData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==';
const contentType = 'image/png';
const byteCharacters = atob(base64ImageData.substr(`data:${contentType};base64,`.length));
const byteArrays = [];
for (let offset = 0; offset < byteCharacters.length; offset += 1024) {
const slice = byteCharacters.slice(offset, offset + 1024);
const byteNumbers = new Array(slice.length);
for (let i = 0; i < slice.length; i++) {
byteNumbers[i] = slice.charCodeAt(i);
}
const byteArray = new Uint8Array(byteNumbers);
byteArrays.push(byteArray);
}
const blob = new Blob(byteArrays, {type: contentType});
const blobUrl = URL.createObjectURL(blob);
window.open(blobUrl, '_blank');
Thanks to Jeremy!

Latest solution - works 2019-10.
Open image in new tab.
let data = 'data:image/png;base64,iVBORw0KGgoAAAANS';
let w = window.open('about:blank');
let image = new Image();
image.src = data;
setTimeout(function(){
w.document.write(image.outerHTML);
}, 0);

You can use document.write() and add html page by yourself. This option allows also to add tab title.
const newTab = window.open();
newTab?.document.write(
`<!DOCTYPE html><head><title>Document preview</title></head><body><img src="${base64File}" width="100px" height="100px" ></body></html>`);
newTab?.document.close();

demo
Updated DEMO (working in Chrome, even with pops blocked) - 3/3/2021
wrapping the call to window.open circumvents the issues detailed below.
document.getElementById('my_button').addEventListener('click', (evt) => {
window.open("https://via.placeholder.com/150", '_blank')
});
Last tested in Chrome 88 on 64 bit Windows 10.
