How to Get to Someone's Photos on Tumblr
- 1). Type the URL for the Tumblr blog that has photos you want to see into your browser's address bar.
- 2). Type "/archive" immediately after the URL. Press "Enter." Your browser goes to that Tumblr blog's archive page, and the pictures are displayed as thumbnails.
- 3). Scroll through the archive. If you find a picture you want to look at, click on its thumbnail image to go to the Tumblr blog post where it is located.
