I have two tables:

settings:
Image_ID INT UNSIGNED NOT NULL

Image
ID INT UNSIGNED NOT NULL,
Width INT UNSIGNED NOT NULL,
Height INT UNSIGNED NOT NULL,
Thumbnail_ID INT UNSIGNED NOT NULL

The Image table stores information about all the images in the database.
If a certain image has a thumbnail, the ID of the thumbnail is stored in the Thumbnail_ID column (otherwise 0 is stored)

The Image_ID column in the settings table defines the ID for an image (which has a thumbnail) which is used a logo in the system.

I would like to extract the following in a single query:
The width & height of the thumbnail image for the image whose ID is stored in the settings table.

I can do this in two queries:
$id = select Thumbnail_ID from image where settings.Image_ID = Image.ID;
select Width, Height from Image where ID = $id;


is it possible to do it in a single query?
maybe the design of the tables is wrong?
what would be a better design?

thanks
