I'm developing my extension Yoshi, but I need the code that will import an image as a costume.
Also, please add it to the source code below:
(function(Scratch) {
‘use strict’;

if (!Scratch.extensions.unsandboxed) {
throw new Error('This extension must run unsandboxed');
}

class YoshiBlocks {
getInfo() {
return {
id: ‘yoshi’,
name: ‘Yoshi’,
// colors
color1: ‘#55aa00’,
color2: ‘#55aa00’,
color3: ‘#000000’, // Yoshi Green
blocks: [
{
opcode: ‘yoshi’,
blockType: Scratch.BlockType.REPORTER,
text: ‘Yoshi!’
},
{
opcode: ‘spawnegg’,
blockType: Scratch.BlockType.COMMAND,
text: ‘spawn Yoshi Egg’,
}
]
};
}

yoshi() {
return ‘Yoshi!!’;
spawnegg()
// CODE HERE
}

Scratch.extensions.register(new YoshiBlocks());
})(Scratch);
