How to Put Titles on Top of a Photo in Tumblrby Alan Sembera
Photo posts are a convenient way to add pictures to your Tumblr blog, but they lack the option to add a title to the post. If you prefer to put titles at the top of all your posts -- even picture posts -- the simplest way is to create a text post, and then insert the photo directly into the body of the text.
Go to your Tumblr dashboard and click the "Text" posting option.
Type the title of your photo in the "Title" field.
Click the camera icon to open the File Upload window.
Select an image file from your computer or from a cloud drive, then click "Open."
Add any additional text and photos you want to include and then click "Post."
