How does Facebook Sharer select Images?

Image
By User


When using Facebook Sharer, Facebook will offer the user the option of using 1 of a few images pulled from the source as a preview for their link. How are these images selected, and how can I ensure that any particular image on my page is always included in this list?

    Put the following tag in the head:

    <link rel="image_src" href="/path/to/your/image"/>


    From http://www.facebook.com/share_partners.php

    As far as what it chooses as the default in the absence of this tag, I'm not sure.

    Old way, no longer works:

    <link rel="image_src" href="http://yoururl/yourimage"/>


    Reported new way, also does not work:

    <meta property="og:image" content="http://yoururl/yourimage"/>


    It randomly worked off and on during the first day I implimented it, hasn't worked at all since.

    The Facebook linter page, a utility that inspects your page, reports that everything is correct and does display the thumbnail I selected... just that the share.php page itself doesn't seem to be functioning. Has to be a bug over at Facebook, one they aparently don't care to fix as every bug report regarding this issue I've seen in their system all say resolved or fixed.

    This is what worked for me: I placed the desired thumbnail image on the page right after the tag and making it too small to see..

    <img src="imagename.jpg" width="1" height="1" />


    I have not tested it with height 0 and width 0 but it probably will still work.. This does not guarantee the user will select this image..

    ALSO it seems like Facebook caches the thumbnails on your page and doesnt always check it for new ones.. try adding this to another page on your site and you'll see that it works.

    I do agree with answers by OffBySome and random.
    My conclusion : Image name should not contain any underscore for grabbing image as thumbnail. It should be one phrase like test.jpg.

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
