Image Syndication
When you post an image to Tumblr, before the image is uploaded to tumblr it can be syndicated to your wordpress or blogger sites. The URL of the page containing the image on your wordpress / blogger blogs can then be used in your tumblr posts.
This allows you to squeeze the user off of tumblr to sites you control where there are no rules on marketing external products.
Example. You could specify to reduce the quality and size of the image published to tumblr with a description "View full size and quality image here <your syndicated URL>"
To specify the blogs to syndicate your images to, check your account, then enter your Wordpress details to the wordpress section in the format:
username,password,proxy,blog-url
and to the blogger section in the format:
username,password,proxy,blog-url
If you enter multiple details, your images will be syndicated to all sites and when it comes to inserting the syndicated link to the tumblr post, a URL is selected at random
Reminder: The token to use in your tumblr post to include the Syndicated URL is SYND_URL. To use a shortened version you can use: SYND_URL_SHORT
