SQL help please

Hi There,

I am perplexed by a query that works on my dev machine but will not work on my web hosts machine.

I have a table of items for sale. I also have a table of product images with a 1-many relationship with the for sale items table.

I want to retrieve every for sale item and the product image with the lowest ID, and if there are no images, I want it to be a null value in the product image field.

the SQL is:
SELECT tblproducts.productID, tblproducts.productTitle, tblproducts.productDesc, tblproducts.productCost, T2.productImagePath
FROM tblproducts
LEFT JOIN
(SELECT * FROM `tblProductImages` WHERE `tblProductImages`.`productImageID` IN ( SELECT MIN(`productImageID`) FROM `tblProductImages` GROUP BY `FK_Product`)) as T2
ON tblproducts.productID=T2.FK_Product

I don't care which product image is retrieved, I just want 1 image (or null) per product. As i said it works on my machine but not on the web hosts.

Any ideas?
