Load an image from file on Android

I need to load images from the device's storage. I have some code that retrieves paths to all the images on the device. This part happens quickly. However, when I use WWW to load the images into Texture2Ds they take more than a second a piece to load. This won't work since most people have hundreds of pictures on their phones. The application also crashes a lot when there are more than a dozen or so pictures. Can someone tell me the proper way to do this or if there is something wrong with my code?

Code (CSharp):

1. public void LoadThumbnailImage(string path) {
2.         WWW www = new WWW(path);
3.         StartCoroutine(LoadThumbnailImage2(www));
4.     }
5.  
6.     IEnumerator LoadThumbnailImage2(WWW www)
7.     {
8.         yield return www;
9.         Texture2D tex = new Texture2D(1, 1);
10.         www.LoadImageIntoTexture(tex);
11.         GetComponent<RawImage>().texture = tex;
12.     }

 

Hi,

I'm not sure if I could help, but I do this to load image to UI

1. public string fileName;
2. public Image Img;
3. 
   
4. IEnumerator Start()
5. {
6. // Load image from mobile
7. byte[] byteArray = File.ReadAllBytes(Application.persistentDataPath + "/" + fileName);
8. Texture2D texture = new Texture2D(8, 8);
9. texture.LoadImage(byteArray);
10. Sprite s = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero, 1f);
11. Img.sprite = s;
12. 
    
13. }

 

Please could you send the code that has a path to all images
