Loading image from file inside an ImageCell

Dear Team,

I have been struggling with loading an image from file inside a ListView containing ImageCells.

The URI methods forks fine for me:
Image = ImageSource.FromUri(new Uri("..."))

I wish I could do the same by using the ImageSource.FromFile method. What I have read in the other topics is that the paths are platform specific, right?

Could someone please point out the correct locations for Android and iOS where I need to put the images in?

Thanks in advance!
