VB 4 -> Xenforo import - attached file import failure

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 17280 bytes) in /home/debtfree/style.debtfreefanatics.com/library/XenForo/Image/Gd.php on line 78

Help? What do I do here?
You will need to increase the memory_limit in PHP to 128M.

Your host should be able to help with that.
Sorry missed this before replying. We have a VM and have full control over that so I went ahead to my master account and bumped PHP to 128 but - could I bump it more? Say to 256M? Just to be safe?
