i have already changed permission to 777 to

ow_static

ow_pluginfiles

ow_userfiles

try using firebug from firefox or inspect element to see if there is any errors returned whilst trying to upload a photo, 

20/2/16 I am getting this problem as well.  If I create and album and drag and drop a picture in it.  It uploads ok.

If I use any of the photo upload links on the site, all I get is a grey bar that pulsates for ever or until I press the browser back button to cancel the upload.

I have set all the recommended permissions to 777 so that should not be the problem.

Turn mod security off

where we can set it?

You need to contact your hosting provider and request to disable mod_security. 

Yoginth, please open your browser console and check whether you have red errors in there while you uploading photos in the newsfeed. Provide the error here. 

Same problem here.

Mark, if you have a flickering line when you try to upload photos, most obvious reason is you have mod_security module enabled on your server, contact hosting provider to disable it
