Facebook POST Image NOT SHOW

WordPress version: 4.2.2

Hi guys, I really really need to get this fixed as I’ve spent more than an entire day trying to fix this to no avail. It’s the biggest roadblock so far as right now we just launched the website thru Facebook pages.

ISSUE/s:
– No image displays when I post/share my site link in social media esp FB.
– Images uploaded in media library when accessed directly leads to 404 (probably causes the above issue) however, the images still show in the media library/website.

OTHER DETAILS:
I did this:
– Installed WordPress SEO by Yoast
– SEO > Social > Facebook > Checked “Add Open Graph meta data”
– SEO > Social > Facebook > Default Settings > Upload Image in Image URL
http://www.dancepinas.com/wp-content/uploads/2015/04/Get-noticed-red.jpg
(size is 1000×1000)
– Open Graph Object Debugger > Fetch new scrape information for http://www.dancepinas.com

I expected the plugin to do this:
– Show all meta data and og tags correctly

Instead it did this:
– all data show correctly EXCEPT FOR OG:IMAGE
– <meta property=”og:image” content=”http://www.dancepinas.com/wp-content/uploads/2015/04/Get-noticed-red.jpg&#8221; /> seems correct HOWEVER…
– og:image does not display an image but it seems it has a link in the blank space. when clicked, it opens the correct image.
– The result of the scraping clearly shows that the image does not display.

I also did this:
– removed image in Default Settings
– uploaded featured image in Home page with the same image

STILL DID NOT SHOW

Last,
– tried several images one at a time in default settings or in featured images in the page
