Add full previews to your twitter feed on WordPress using Ozh’ Tweet Archiver

Ozh’ Tweet Archiver is a WordPress plugin that can archive your tweets on your own blog; it simply creates a new post for each tweet. Additionally, it offers converting hashtags to WordPress tags, and several other features. Nevertheless, one feature, I thought might be interesting, is to process the links on tweets and show them as a Facebook feed. Recently, I modified the code and it worked very well on my blog: Gadelkareem Tweets.

– All we need is to modify the “wp-content/plugins/ozh-tweet-archiver/inc/import.php” file as following:
