prettyPhoto Media stopped working

Dear forum members,

I made a custom WordPress theme and tried to make prettyPhoto Media working. At first it did not work because of missing hooks wp_footer() and wp_head(). Then I added wp_footer() and everything worked until I added wp_head() – now it does not. jQuery seems to be loaded correctly. Could you please help me?

Head section contains:
