Advanced Random posts widget for Blogger with image thumbnails and snippets

When your blog has too many posts, visitors don't always have the time or desire to go through all the posts written there in order to make an idea of the blog's content. Thus, a random posts widget that will allow visitors to find content more easily could be really useful. This tutorial will show you how to add a random posts widget to display a list of posts in a random order with thumbnails and excerpts.

  • Summary length: you can control the the length of the summary (in characters) by changing the 110 value from var randomposts_chars=110;
  • Post info: if you want to hide the post date and comment count change 'yes' from var randomposts_details='yes'; to 'no';
  • Font Size for Posts Titles and Summary: to modify the font size for the post snippet modify the 11px value and for the posts title, the 12px value;
Click on the "Save" button and View your blog. The sidebar will display a random posts widget on each of your blog pages.

  5. Oh, it just hit me, I have this ''DISQUS'' widged/comment manager and maybe that was the problem because this random post widget uses the comments as part of the whole...

    1. Hi there,

      You could try this script instead and change 3 from var rdp_numposts=3; with the number of posts to be shown. Make sure that you don't set up more posts than those you have published on your blog. I hope it will work now. Thanks for visiting!

  20. Love it! Thank you (www.grintage.blogspot.com) One question though: Right now the thumbnails are all vertically alligned, is there a way for me to display them next to each other, like in two columns, so instead of having 6 vertically alligned images, I'd have 3 pairs.

    2. Hi Mike,

      You can also add display: none to "rp-snippet" class in this line:
      .rp-snippet {font-size: 11px;background: none; padding: 5px; margin-right: 8px; display: none;}
      It can be found between the <style>...</style> tags.

  29. hi. sorry for commenting as anonymous, i'm on a hurry, just wanna say this works for me, but like one of the previous commentors, I found out that the images for certain posts won't show. So far I only have one post which image won't show on the Random Post box, it's the newest post.

    Please let me know how to fix these, I'm sure some others up there are having the same problem too. Thank for creating this widget and helping us out! Cheers!

  30. Thank you very , much, is working perfectly!

  31. Thank you, it's working. The only problem is the font size of the post titles, nothing happens when i try to change it..it doesn't matter if i change it from 12px to 11px or 10px,i see the same font size..i guess there is a setting on my template which overrides all the font size on the footer, but the comments fonts size value it's working.
    Thanks for this great widget, i will put a link on the footer for new blogger to bring them here for hints.
