Drawing images into a window?

[Drykul]

I feel like I'm just missing something and I'll have a slap my forehead and say "Duh!" moment, but I can't figure out for the life of me how to draw an image in a window similar to how icons and character faces in Window_MenuStatus... is there not a built in method for using blt to draw images from the picture folder into a window already?

Edit - I ended up writing my own little code snippet for it but I was still wondering if I was just missing something?

Spoiler: Window_Base.prototype.drawPicture

Window_Base.prototype.drawPicture = function(pictureName, x, y) {
    var bitmap = ImageManager.loadPicture(pictureName);
    var pw = bitmap.width;
    var ph = bitmap.height;
    var sx = 0;
    var sy = 0;
    this.contents.blt(bitmap, sx, sy, pw, ph, x, y);
};
