GifGities is a funny and weird site that gives you free animated gifs for almost everything. Contains over 4.500.000 animated images.
Try it for free machine Internet Archive animated GIF search. Enter the GifCities.org where you can search by any term you want. You can search for butterflies, balloons, cats, dogs, stars, etc.
The search is better done in the English language. If that doesn't work then you'll see a GIF of a penguin cuffing another penguin.
But if there are results, you'll see your screen full of animated GIFs. If you click on a GIF, then it takes you to the web page from Wayback Machine that contains the given GIF.
You can of course download any GIF you see on your screen as a photo (it's a GIF after all). The image of the article is the search results for the term "dog".
For the record, the animated GIF was probably the most iconic file type of the early web, circa the 1990s. Still, they're smart, small in size, and still as popular today as they were twenty years ago.
