I'm trying to upload some torrents to raise my ratio. While I'm trying to upload it, I get this error on a blank page:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 286191 bytes) in /data/gt/shared/www/html/include/benc.php on line 220

I don't know what it means or what i have to do to fix it. I uploaded 10 pictures, does it mean the pictures surpass the file size limit? Any help would be greatly appreciated!
