Preview not showing full photo

On my desktop (on my phone it isn’t showing up at all I figure it just takes time). This is problematic because you have to download a photo before deciding whether to delete it.

To be specific the full dimensions are not shown, it is cropped more square and it is lower quality and pixelated.

Does this happen when you click/press/preview the photo online in your app or are you referring to the thumbnail of the image?

When I click on it online or on the app. These are iPhone camera photos. Screenshots do show the full dimensions.

Is this not the full image you are trying to view?

No the photo is rectangular. That said I seem to have found a workaround that is obvious is retrospect, opening photos through my Icedrive folder in file explorer (which opens them in the usual Windows photos viewer)
