Show HN: Thumbnail.ai – Automatically generate thumbnails for your blog posts

Every time you accept user-controlled input you need to think about filtering, and sanity-checking.<p>For example:<p><a href="https:&#x2F;&#x2F;thumbnail.ai&#x2F;create?link=http:&#x2F;&#x2F;127.0.0.1&#x2F;server-status" rel="nofollow">https:&#x2F;&#x2F;thumbnail.ai&#x2F;create?link=http:&#x2F;&#x2F;127.0.0.1&#x2F;server-sta...</a>

Damn that is useful. I love it. Just put in a URL to a blog post of mine that had an infographic, but not a featured thumbnail, and it pulled in something from the infographic, and created it for me. I like it. thanks for sharing! Though I think I&#x27;d like an option where it doesn&#x27;t pull the logo from my site and just gives me the image.

Hi HN, I built this MVP because using an image editor to create thumbnails for my blog posts was time consuming.<p>Good thumbnails can bring a lot of traffic to a post specially when shared on social networks. There are just 4 templates now and will add more. Would love your feedback.
