When i share  to facebook the image how take its the default image "

ow_userfiles/plugins/social_sharing/default.jpg "

I believe this happening when i share with preview image the small one, i tried resize to 400 for full image but still dont work , I cant add to blogs full images like 600 or 1200 pixels are huge

What blogs are you you referring to? Where do you try to add images to blogs? Please provide screenshots

As to this one:

Also i notice that , when i try to share a member link without the plugin  , facebook take only the texts

When i run debug on facebook the problem gone and i can add to facebook with the profile picture 

This is called facebook cache which you need to clean by running a debugger. 

lets try share to facebook one of users profile here on oxwall 

oxwall.org/users

copy one link and try share to facebook, no image picture cached , now run the same profile to

developers.facebook.com/tools/debug/

and try again ... 

The debug add a picture but its not the correct one , its not the same as the profile

This is not a bug this is how it works in the meantime, You should check this section: 

When shared, this is what will be included 

of the debugger to see what's going to be shared. 

That happens because there's no og:image meta info on the profile page
