MS SQL MAX QUERY, how do I return "multiple" MAX values in one query?

I have two tables.  One contains a big pile of product information as well as the page number that the item appears in, in a catalog.  The second table contains the imagePath for the items, but each item has two images associated with it.  One is low res, the other high res.  Using the supplier code, how do I return only the high res imagePaths for each code?  I feel that MAX is the right path to proceed down, but I'm probably wrong.

SELECT MAX(tblImagePaths.fldItemSize) AS LargeImage, tblSupplierData.fldPage, tblImagePaths.fldItemCode
FROM tblSupplierData
INNER JOIN tblImagePaths ON tblSupplierData.fldItemCode = tblImagePaths.fldItemCode
WHERE (tblImagePaths.fldItemCode, 5) = @monthYear) AND (tblSupplierData.fldPage = @pageNumber)
GROUP BY tblImagePaths.fldItemSize, tblSupplierData.fldPage, tblImagePaths.fldItemCode

Use CTE to prepare the statement for the hi-res images:

;with CTE as
(
SELECT tblImagePaths.fldItemCode,
tblImagePaths.fldImagePath,   -- <-- Please put here the proper column name for the Image Path
ROW_NUMBER OVER(PARTITION BY tblImagePaths.fldItemCode ORDER BY tblImagePaths.fldItemSize) row_num
FROM tblImagePaths 
)
SELECT tblSupplierData.fldPage, tblImagePaths.fldItemCode, 
CTE.fldImagePath   -- <-- Please put here the proper column name for the Image Path
FROM tblSupplierData
INNER JOIN CTE ON tblSupplierData.fldItemCode = CTE.fldItemCode AND CTE.row_num = 1
WHERE (tblSupplierData.fldItemCode, 5) = @monthYear) AND (tblSupplierData.fldPage = @pageNumber)

I have not tested it, but pretty sure it should work once you put the proper column name for Image Path

Just to clarify my question.  If the user selects a page number from a particular catalog, then I'm trying to return ALL items on that page and their respective highest resolution images.  So the result set would be something like
Page 5, Item 65, Imagepath c:\etc, etc
Page 5, Item 66, Imagepath c:\etc, etc
Page 5, Item 67, IamgePath c:\etc, etc
