Getting an image URL from a message - node.js

Question

I want to get the image URL or the image itself from a message, and put it in my embed. I have no idea to do it myself, hope you can help me :)
client.on('messageReactionAdd', (reaction, user, message) => {
const eggsa = client.emojis.find(emoji => emoji.name === "eggsa");
if (reaction.emoji.name === 'eggsa') {
const msg = reaction.message;
const guild = msg.guild;
const guildMembers = guild.members;
const guildMember = guildMembers.get(user.id);
if (!guildMember.roles.some(r=>["Leder"].includes(r.name)) ) return guildMember.send(" ',:^\\ ");
const message = reaction.message;
const kanal = reaction.message.guild.channels.find('name', 'sitater');
var embed = new Discord.RichEmbed()
.setDescription(message.content)
.setTimestamp()
.setFooter(message.author.username, reaction.message.author.avatarURL)
.setImage()
kanal.send({embed});
}
});

You can simply use the .attachments property from the message object. This returns you all attachments of this message included all pictures. From there on, you can use the property .url and this gives you the image url that you can add in your embed.
In the following code I added a check if there are even attachments. If yes, add the first image url as image of the embed.
Here is the code:
client.on('messageReactionAdd', (reaction, user, message) => {
const eggsa = client.emojis.find(emoji => emoji.name === 'eggsa');
if (reaction.emoji.name === 'eggsa') {
const msg = reaction.message;
const guild = msg.guild;
const guildMembers = guild.members;
const guildMember = guildMembers.get(user.id);
if (!guildMember.roles.some(r => ['Leder'].includes(r.name))) return guildMember.send(" ',:^\\ ");
const message = reaction.message;
const kanal = reaction.message.guild.channels.find('name', 'sitater');
const embed = new Discord.RichEmbed()
.setDescription(message.content)
.setTimestamp()
.setFooter(message.author.username, reaction.message.author.avatarURL);
if (message.attachments.size !== 0) {
embed.setImage(message.attachments.first().url);
}
kanal.send({ embed });
}
});
