1. Search the image you want to get a URL for.
For example, search the term "Cat" in Google Images.
2. Right-click on the image to open the menu.
3. Click ‘Copy Image Address’ in the menu.
It can look long and funky, like this: https://upload.wikimedia.org/wikipedia/commons/thumb/1/15/CatAugust2010-4.jpg/1200px-CatAugust2010-4.jpg
4. Paste the address you copied into Threadly.
If the image is valid, it will load and display a preview on your Threadly screen.
