Sending local image

[Kojobu]

My goal is to generate a plot from data and send the final image in the channel where the slash command was executed. So far everything works, except I'm unable to send the image.

I first registered the slash command, this works flawlessly but then when I want to execute it, it times out every time. Unfortunately, I couldn't find any similar example.

"b-field": func(s *discordgo.Session, i *discordgo.InteractionCreate) {
	s.InteractionRespond(i.Interaction, &discordgo.InteractionResponse{
		Type: discordgo.InteractionResponseChannelMessageWithSource,
		Data: &discordgo.InteractionResponseData{
			Content: "Here's the local B-field of my room:",
			Embeds: []*discordgo.MessageEmbed{
				{
					Image: &discordgo.MessageEmbedImage{URL: "PATH/plot.png"},
				},
			},
		},
	})
},

I'm not sure if embeds are the right approach here, but I couldn't find a better one. Btw, when entering a URL to an existing image uploaded on the internet, it works without complaining. I would tremendously appreciate some help.

Local image path doesn't work in any situation, you may have to upload the file on the internet and set the URL accessible publicly.

Isn't there really no other way? It's hard to imagine that such a comprehensive package as discordgo doesn't provide any opportunity to attach local images to a message.

Found a solution by changing the function as follows:
Although I would like to have it as an embed, this works at least.

"send_image": func(s *discordgo.Session, i *discordgo.InteractionCreate) { // <--- Stop using Single Letter Variable Names >:(
			fmt.Println("send_image.go: send_image() called")
			fileName := "PATHTOFILE"
			f, err := os.Open(fileName)
			defer f.Close()
			s.InteractionRespond(i.Interaction, &discordgo.InteractionResponse{

				Type: discordgo.InteractionResponseChannelMessageWithSource,

				Data: &discordgo.InteractionResponseData{
					Content: "Here's the local B-field of my room:",
					Files: []*discordgo.File{
						&discordgo.File{
							Name:   fileName,
							Reader: f,
						},
					},
				},
			})
		},

You can use attachment://filename (where filename is the Name you provided in the File struct) if you want to reference it in embeds.
