1) your base64 encoded string probably is not fully valid. you can try to use this code instead of atob

var decodeBase64 = function(s) {
    var e={},i,b=0,c,x,l=0,a,r='',w=String.fromCharCode,L=s.length;
    var A="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
    for(i=0;i<64;i++){e[A.charAt(i)]=i;}
    for(x=0;x=8){((a=(b>>>(l-=8))&0xff)||(x<(L-2)))&&(r+=w(a));}
    }
    return r;
};

2) I think it should be image = image.replace(/^[^,]+,/, '');

3) As far as I know, support of the Blob in IE starts from version 10 - https://developer.mozilla.org/en-US/docs/Web/API/Blob
