optimization

I'm so bad in making good MySQL queries. I've created this one:

http://pastebin.com/GtDfgky8

products Table have about 17k rows, allegro Table have about 3k of rows.

The query Idea is select all products, where stock_quanity > 3, where is photo, and where is no product id in allegro table.

Now query takes about 10 seconds... I have no idea how I can optimize this query.

Please help my, I'll be thankfully! :) & Sorry for my bad English also
