I suspect you want to tokenize each of the values, combine the results, and
then de-duplicate. That would be

> distinct-values(($jpg_list_1, $jpg_list_2, $jpg_list_3) ! tokenize())

Alternatively you could concatenate the strings (with space separation) and
then tokenize the result:

> distinct-values(tokenize(string-join(($jpg_list_1, $jpg_list_2,
$jpg_list_3), ' '), '\s+'))
