Opening an image directly from URL

[No-Cellist-7780 (Swapnadeep Som)]

i would like to open an image file from a url directly without downloading it, however cant seem to find libraries that would help me do that. my package code till now is below

package browser

import (
   "encoding/json"
   "errors"
   "fmt"
   "io/ioutil"
   "net/http"
   "strconv"
)

type Reddit struct {
   Kind string `json:"kind"`
   Data Data   `json:"data"`
}
type Source struct {
   URL    string `json:"url"`
   Width  int    `json:"width"`
   Height int    `json:"height"`
}
type Content struct {
   Selftext string `json:"selftext"`
   Title    string `json:"title"`
   Downs    int    `json:"downs"`
   Ups      int    `json:"ups"`
   Score    int    `json:"score"`
   URL      string `json:"url"`
}
type Children struct {
   Kind string  `json:"kind"`
   Data Content `json:"data"`
}
type Data struct {
   Children []Children `json:"children"`
}
//HTTPRequestCustomUserAgent bla bla
func HTTPRequestCustomUserAgent(url, userAgent string) (b []byte, err error) {
   req, err := http.NewRequest("GET", url, nil)
   if err != nil {
   	return
   }

   req.Header.Set("User-Agent", userAgent)

   client := &http.Client{}
   resp, err := client.Do(req)
   if err != nil {
   	return
   }
   defer resp.Body.Close()

   if resp.StatusCode != 200 {
   	err = errors.New(
   		"resp.StatusCode: " +
   			strconv.Itoa(resp.StatusCode))
   	return
   }

   return ioutil.ReadAll(resp.Body)
}

func Parse(url string) {

   var reddit Reddit
   b, err := HTTPRequestCustomUserAgent(url, "Mozilla")
   if err != nil {
   	fmt.Println(err)
   }
   json.Unmarshal([]byte(b), &reddit)
   for i := 0; i < len(reddit.Data.Children); i++ {

   	text := string(reddit.Data.Children[i].Data.Selftext)
   	img := string(reddit.Data.Children[i].Data.URL)

   	fmt.Println("Title :", reddit.Data.Children[i].Data.Title)
   	fmt.Println("Upvots :", reddit.Data.Children[i].Data.Ups)
   	fmt.Println("Downvotes :", reddit.Data.Children[i].Data.Downs)
   	if text == "" {
   		fmt.Println("Content :", img)
   	} else {
   		fmt.Println("Content :", text)
   	}
   }
}

I would like to open the image content in my default image viewer directly from the URL.
Thanks in advance
