var oneWeekAgo = Math.round((new Date().setDate(new Date().getDate()-7)) / 1000);
FB.api(
{
method: 'fql.query',
query: 'SELECT pid, caption, aid, owner, link, src_big, src_small, created, modified FROM photo WHERE aid IN (SELECT aid FROM album WHERE owner IN (SELECT uid2 FROM friend WHERE uid1=me())) AND created > ' + oneWeekAgo + ' ORDER BY created DESC LIMIT 20'

function(response) {
alert('Photos: ' + JSON.stringify(response));

Answer
Do something like this:
FB.api({
method: 'fql.multiquery',
queries: {
'query1': 'SELECT uid2 FROM friend WHERE uid1 = me()',
'query2': 'SELECT vid, owner, title, description FROM video WHERE owner IN (SELECT uid2 FROM #query1)'
}
},
function(response) {
// response should have 2 objects in it, both containing an fql_result_set
// array with the data and the name you entered for the query (i.e. 'query1')
alert('Photos: ' + JSON.stringify(response));
});
