I am using picasso in my recycler view. I am wondering about the caching: When I scroll down the images disappear and when I scroll up again, they show again. But its displaying the progress bar for downloading and it takes like a second to show it.

my code

```
                Picasso.get().load(profileUrl).placeholder(R.drawable.placeholder_image).fit().into(postViewHolder.profileImg);

```

I want to avoid downloading the same images multiple times. Or is it just the caching that takes some time to display the already cached image again?
