How to convert images to links in Go

In Go, we can use third-party libraries to easily convert images for links. Here is an example using the [cloud.google.com/go/storage](https://godoc.org/cloud.google.com/go/storage) library:

1. Import Library

import (
    "context"
    "fmt"
    "log"

    "cloud.google.com/go/storage"
)

2. Create storage client

ctx := context.Background()
client, err := storage.NewClient(ctx)
if err != nil {
    log.Fatalf("storage.NewClient: %v", err)
}
defer client.Close()

3. Get the image to convert

bucketName := "my-bucket"
objectName := "my-image.png"
obj := client.Bucket(bucketName).Object(objectName)

4. Generate a link

link, err := obj.SignedURL(ctx, &storage.SignedURLOptions{
    Method:      "GET",
    Expires:     time.Now().Add(15 * time.Minute),
    ContentType: "image/jpeg",
})
if err != nil {
    log.Fatalf("Object(%q).SignedURL: %v", objectName, err)
}

The generated link variable is a string containing a link to the converted image.

5. Using links

You can use the link variable where needed, such as HTML <img alt="How to generate links for golang images" > Tags:

<img  src="<%= link % alt="How to generate links for golang images" >" />

Using this method, you can easily create image links in Go and share them with others.
