 like BuddyPress will be very appreciated.


 Hi @azaozz

 Just tested your patch with BuddyPress trunk :
 - regular WordPress
 - WordPress Multisite (having BuddyPress activated on the network or not)
 - I've also run the BuddyPress phpunit testsuite regular/multisite.

 All tests are ok and everything seems to work fine for BuddyPress uploads
 (avatars & cover images).
