Broke my Gallery trying zip functionality

[olegario]

I tried installing the zip hack, and didn't appear to work, so I reverted back all the files that were changed.  But after clicking around, when trying to view a pic, I get this error message at the top:

Warning: Wrong datatype for second argument in call to in_array in /var/www/html/photos/displayimage.php on line 278

and this error message where the pic should be:

Fatal error: Call to undefined function: display_film_strip() in /var/www/html/photos/displayimage.php on line 607

And nothing below it.  The index.php looks fine as I'm able to see the album lists, but looks like displayimage.php and thumbnails.php don't work.  

Any ideas?  I don't mind just reloading all of the original php files, but I'd like to try and fix this if possible.

Thanks.
