Security cam blog posts on Tumblr

Conclusions and Future

Now, the Tumblr features come into play. Line 31 reads the YAML file with the tokens, and line 33 creates a new object of the WWW::Tumblr type. Drawing on the Tumblr API, line 43 then retrieves the details of the previously defined test blog (schtonk.tumblr.com) and the post() method sends the image file content to the Tumblr server, specifying the type as photo. Then, $post indicates success with a true value. If you then launch the script by typing ./tumblr-post, the response is the ID of the newly created blog entry:

I have published post id: 63791478637

Unfortunately, the API provides no way to attach an image caption. This method currently seems to work only via a browser interface that allows HTML pages with embedded photos. Theoretically, however, the script could upload text and reference the images on a different server. For the surveillance photos, however, it is more convenient for me to store the images on Tumblr.

A viable alternative would be a caption in the image itself, as presented in last month's Perl column using the CPAN Imager module. In this way you could add brief texts to the image – for example, the current outdoor temperature.
