Make a Discord bot reply when a user sends an image in chat (continued)
I have a discord bot up and running and working on slash commands. But I'm having trouble getting it to reply when someone sends an image. I posted this yesterday where I couldnt get the discord bot to respond if someone uploaded an image.
A member of the discord helped me out(thank you again). however, Ive run into another issue. My bot cannot distinguish the type of attachment sent. If I tag someone in a message: i.e. "@someone what's up" the bot responds. I only want the bot to respond if a .png or a .jpeg is sent into the channel.
currently my code looks like this:
if (message.attachments){
message.channel.send('everyone It looks like someone is sending something you like 😉 ');
}
If you can help i'd be in debt to you forever!!

Codeblocks:
```js
const Discord = require("discord.js");
// further code
```
becomes
Inline Code:
`console.log('inline!');` becomes
console.log('inline!');thats the full thing. If i tag someone that error happens

thats why it was crashing when i was just tagging someone
because tagging someone counts as an attachment for some reason
