Firebase: cloud storage high bandwith

I'm making a Flutter app that is like social media, so uses pictures a lot. With that in mind, looking at the Firestore data, the reads with about 15 people look like this: enter image description here

But they are far outpaced by my storage bandwidth usage: enter image description here

I'm thinking about possible reasons why this is the case. First, I am not sure if this could potentially be a problem, but I save each user's images into a respective folder: enter image description here

Furthermore, looking through the images, I notice that file sizes average around a few hundred kilobytes, with a few being sized in megabytes, the largest I found is 9 MB. Are these too large?

Are there any other ideas I am missing? I am trying to implement caching on my front end to help with this problem, but I am open to any other possible reasons and solutions.

If you take a look, at the major social media apps, the average size is around a few tens of kilobytes and not a few hundred kilobytes. If you look at Instagram for instance, all images are around 40-50 kilobytes.

With a few being sized in megabytes, the largest I found is 9 MB. Are these too large?

Way too large.

Yes, resize the images before uploading them to storage.

For not reading an image from the server, each time the user uses your app, a caching mechanism will be helpful. However, it will not help the first time the user opens the app. When indeed it is needed to be downloaded.

Instead of having a single 9 MB image, it's better to have 180 images of 50 KB.
