the images should not be stored in the database using the blob data type.
In your products table, create a column for the productImage
in that column, store the image file name:
myProduct.jpg
the files should be stored in a folder on your site, for instance:
productImages/myProduct.jpg
the productImage column in the products recordset will return the file name. in your img tag, you can use the data from the recordset:
<img src="productImages/<?php echo $row_RecordsetName['productImage'] ?>" />
