I just want to understand .. when you say,

"Every uploaded picture for avatar becomes blurry.."

AND

"Look at this picture.. Circled is my profile photo.. Ive uploaded several in my wpforo forum profile and they always blurry when i do.."

Did (or do) you mean, the background of the avatar?

Because I think, by default, the background of the picture or image  INSIDE the avatar, is "expanded" as a background blurry (or grainy) design.

If you want to hide the blurry background of your image / avatar, you can go to:

1. Forum Dashboard
2. Settings
3. Styles
4. then on the "Custom CSS Code" add the code below:

#wpforo #wpforo-wrap .wpforo-profile-wrap .wpforo-profile-head-bg {
background-color: lightgray;
background-image: none !important;
}

#wpforo #wpforo-wrap .wpforo-profile-wrap .wpforo-profile-head-bg .wpfx{
display:none;
}

NOTE: You can change the "background-color: lightgray;" above to whatever color you want to match your Forum Theme Colors.  Your Avatar or Image will just upload as is.  

Let me know if that works for you. (It worked for me on my Forum, just sharing some tips I learned along the way).

Good luck and God bless you!
