SQL count is not upto my desired result

I have two different table Products and ProductImages: 

SELECT COUNT(p.productid) AS product_count, COUNT(pi.imageid) AS image_count  
FROM [Products] p, [ProductImages] pi  
WHERE p.productid=126 AND pi.productid=126;

Above query is giving me the mulitplication of both counts in each COUNT. Please guide me where I am wrong and Can I do it with single select query.

SELECT  COUNT(DISTINCT p.productid) AS product_count ,
        COUNT(DISTINCT pi.imageid) AS image_count
FROM    [Products] p ,
        [ProductImages] pi
WHERE   p.productid = 126
        AND pi.productid = 126 ;

You can get this in two rows 

SELECT COUNT(p.productid) As Count
FROM [Products] p
WHERE p.productid=126
UNION All
SELECT COUNT(pi.imageid) As Count
FROM  [ProductImages] pi 
WHERE pi.productid=126;

OR you can do this without UNION ALL

SELECT 
(SELECT COUNT(p.productid) As Count 
From [Products] p WHERE p.productid=126) ) as t1,
(SELECT COUNT(pi.imageid) As Count 
FROM  [ProductImages] pi WHERE pi.productid=126) as t2

Try This by subquery

SELECT COUNT(p.productid) AS product_count,(Select COUNT(pi.imageid) AS image_count  [ProductImages] pi  Where pi.productid=126; ) FROM [Products] p  WHERE p.productid=126
