No need to write the join conditions twice in the query. Is this what you
want...

SELECT PictureName, ProdName, Description, SalesPrice
FROM Products
INNER JOIN ProdCategory USING(CategoryNr)
INNER JOIN ProductsPics USING(ProdNr)
WHERE ProdCategory.Category = $category;

ie only rows with matches across the 3 tables, scoped by $category?
