my spray doesnt show to other people (?)

hello, i have a problem with my spray. I used to have an old spray so i wanted to change it. okay, everything fine, i imported the pic i wanted to use, joined a server and used the spray. but my friends weren’t seeing my spray, i dont know why. I changed back to my old one and it worked. I still have no idea why my newer one doesnt show up. help :\

Make sure the server has both sv_allowupload and sv_allowdownload set to 1.

im not sure that will solve the problem, i can see other ppls spray, i can even see mine, but others cant see mine. i will try anyways, thanks
