The microblogging site Tumblr allows you to post text, links, images, videos and audio to a custom domain you create when signing up for the service. Although Tumblr doesn't limit the amount of storage space available to you, it does impose restrictions on how much content you can post per day. These limits are set to protect against spam posts.

Tumblr Restrictions

Tumblr restricts the number of posts you can upload to your blog to 250 per day. Uploaded images are restricted to 75 posts per day, and files can be no larger than 10MB, or 1MB for GIF files. The limit resets every night at midnight Eastern StandardTtime. There is no set limit for the amount of overall storage space you can use, but you cannot post more than the daily limit. A full list of Tumblr's restrictions can be found on its community guidelines page (link in Resources).
