This article explains two ways to search for X (formerly Twitter) images. Instructions apply only to X.com in a desktop or mobile web browser.
Go to X.com in a web browser and locate the Search X field at the top of the screen.
Type a search term related to the images you want to find. For example, if you want to find images of dogs, you can simply type "dogs." As you type, results will appear in the column below the search field.
Select Photos at the top of the screen to filter all tweets except those with images that match the search term.
