The handler is responsible for sizing the image.  The reason for this is
that the preview does not have to be an image -- it can be any kind of
overlay decoration.

If you decide to use an image file as the preview, you can call
`org-link-preview-file' inside your handler to handle the geometry for
you.  This includes the size and alignment specified by #+attr_*
keywords, `org-image-max-width' and `org-image-align'.

If you are using a preview image from image data, you'll have to copy
some of the code in `org-link-preview-file' to your handler if you want
to respect these user options.

I don't follow.  What do you mean by "it doesn't get the contents"?  Did
the preview work as expected when you used a prefix arg of 1?
