If pixiv photo uploaded to Dropbox, then create a photo post on Tumblr.
Automate your queuing of photos from pixiv by uploading them to Dropbox. Recommended for auto-queuing your photos. Features: 1. Auto-tagging. 2. Automatic linking to source page. Important notes: 1. All photos must be named with their respective illust_id (refer to the URL in the illustration page on pixiv). 2. Mangas or multi-images illustrations are not supported. You will have to upload them one-by-one as IFTTT does not support regex to filter the pages number after the illust_id.
