Answer 1

you can use ImageArtist which a GD wrapper created for making image manipulation insanely easy with php

$overlay = new Overlay(720, 480, new Color(34,34,36));
$w = $overlay->getWidth();
$h = $overlay->getHeight();

$mi = new CircularShape("./mi.jpg");
$mi->scale(21);
$mi->setAxises(60,60);
$mi->build();

$mali = new CircularShape("./mali.jpg");
$mali->scale(60);
$mali->setAxises(140,140);
$mali->build();

$bach = new CircularShape("./har.jpeg");
$bach->scale(40);
$bach->setAxises(80,80);
$bach->build();

$borderd = new CircularShape(new Overlay($bach->getWidth()+10,$bach->getHeight()+10,new Color(255,255,255)));
$borderd->build();
$bach = $borderd->merge($bach,5,5);

$img = $overlay->merge($mi,$w/2 + 60,120);
$img->merge($mali,170,60);
$img->merge($bach,$w/2,200);

$img->dump(); //this just for demo, but you can use other methods to save this to disk

at the moment ImageArtist does not support borders but if you be little creative you can use an overlay instead. here is the output of the above code.
