Facebook Thumbnails Issue Traced to safe_image.php

For some reason, facebook's safe_image.php script isn't generating thumbnails, properly. It's generating a 1x1 image... even though the correct image is linked in the script's parameters. Example:

<img class="img" alt="" src="https://s-external.ak.fbcdn.net
/safe_image.php?d=AQBtrCt_Es_KsED0&w=90&h=90&url=http%3A%2F
%2Fwww.southlapatriots.info%2Fimages%2FScamra%2FJayCastilleCouncil2.jpg"

The linked image is correct, but it is still only generating a 1x1 image.

Got the same problem today, in my case was an https issue.

I automatically redirect every http requests to https, and while the browser works this out normally, FB's safe_image.php doesn't. If you have such redirect as well, you may want to disable it for just your og:image file.

I also get into a similar problem. My problem is because of the image name has a "space" in it. so it is not appear in the facebook debugger and also in sharing.

So i fixed the issue by replace space with hyphen("-") through coding part. After that i debug the url in facebook debugger, it appears. That means Facebook wont show the image name with "space". But there is no logical reason behind this. Anyway it will help someone.

For more information check this answer posted by Patrick D'appollonio. It helps me.

Are you using any sort of gzip compression for your images? We are seeing a similar issue, but we compress our image with gzip and set the headers. Browsers are rendering fine, but Facebook is essentially displaying nothing.

Jay, I just checked for compression, and i'm pretty sure it's not compressed. Deflate and Header are not enabled and Joomla is not running any type of compression. – Hentrich 11/11, 2011 at 2:27

safe_image script code doesn't support having a % in the app's image url (which is probably why the image turns into a 1x1 transparent pixel)

so the solution is here . Try to follow the instruction in the first comment by chris

If you're referring to the comment about the time stamp, the original image doesn't have one. The original meta looks like this: <meta property="og:image" content="southlapatriots.info/images/Scamra/…> It's the safe_image.php script code that's inserting the "?" – Hentrich 10/11, 2011 at 21:57

In my case, the directory including genuine targeted images is under ".htaccess" control, in which images being called from external server is prohibited.

Example of blocking ".htaccess" file such as:

<FilesMatch "\.(jpg)$">
SetEnvIf Referer "^http://www.mysite.jp" ref_ok
order deny,allow
deny from all
allow from env=ref_ok
</FilesMatch>
