Memory problem importing media library

Hi there,

I am using the wordpress importer to import my site from wp.com. I get through some of the media before I get this message:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 21352826 bytes) in /home/gooda814/public_html/balcatta/wp-includes/class-http.php on line 1106

What can I do to get around this?

Thanks – Mark
