Select Multiple Images Using Department Field In Spriden Table To Pull Needed Id Numbers

I have an Oracle 10g database, on the App Serv I have an image file that has 20,000 .jpg files that has an id number as each image name.I have successfully queryed the image file and posted one image to my web page matching the image id number.
sample:

select substr(spriden_last_name,1,20)||', '||
substr(spriden_first_name,1,20)||' '||
substr(spriden_mi,1,1) stname,
'<img src = "/images/&1..JPG" width="400" height="400"/>' pic
from spriden
where spriden_id = '&1'
/

the &1 is the matching id number that is input from the user.My task now is to select multiple images using a department field in the spriden table to pull the needed id numbers.I have not been successful in the proper format to pass the id number to the <img src field.
