Well, it's pretty straight foward. All I did was add the case statement to your original query:

SELECT * FROM stats_new WHERE is_pot = '1' OR is_sr = '1' ORDER BY RAND() LIMIT 1

SELECT *, CASE WHEN is_pot = '1' THEN 'image_pot' ELSE 'image_sr' END AS clan_image FROM stats_new WHERE is_pot = '1' OR is_sr = '1' ORDER BY RAND() LIMIT 1

If I fill this in with actual values and turn it into php code it might look like this:
PHP Code:
$clan_result $db->query_first("
    SELECT *, 
    CASE WHEN is_pot = '1' THEN '" 
DIR "/images/clan/pot.jpg
    ELSE '" 
DIR "/images/clan/sr.jpg' AS clan_image 
    FROM " 
TABLE_PREFIX "stats_new
    WHERE is_pot = '1' OR is_sr = '1'
    ORDER BY RAND() LIMIT 1
"
);

echo 
"<img src='" $clan_result['clan_image'] . "' border = '0'/>"
