Solution 1

you can get the query string using Request.QueryString()
but i cant figure out the location from where you want to download the image from. Is your image/pdf files in your database? or your query string contains the path to it. Please be specific.

Solution 2

Images are stored in sql server as BLOB data type. So query the table, get the value from that column and convert it to appropriate type (Image stream or other input stream) and bingo, you get the file.
