Holder renders image

Placeholders can have custom colors, fonts, resizing behavior, and rendering engine.

DEMO

function charsRandom(len, chars) {
    chars = chars || "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    len = len || 1;
    var cr = [],
        L = chars.length;
    while (len--) cr[cr.length] = chars.charAt(Math.floor(Math.random() * L));
    return cr.join(''); // or return the array cr
}

function getHolder() {
    //alert("holder.js/300x200/random/text:" + charsRandom());
    return "holder.js/75x75/random/text:" + charsRandom();
}

$('img').attr({
    "data-src": getHolder()
})
