You can use 'Contains' (as a condition in the Server Connect query that populates your Select) and in the pages Select have no value but text (Show All) for the first option in your select and populate the select list with your query for the remaining photos using their id's as the value (maybe a uid or whatever you use) and the photo title as the text. This way on initial view all the images will be shown, and then upon selection only the selected will display.
Don't forget when you add the Action to your page to specify the Select List as the filter!
