pfps ??

hii! (were gonna ignore the layout of this post im struggling to get pictures to work ;;) is there anyway to get my pfp to work? ive noticed alot of other peoples pfps glitching too n not showing up n i was just wondering if anyone knew if it was fixable? or if its just a glitch that happens and theres nothing i can do? i hate seeing the silly grey icon on my profile ,, LOL
