If you're looking to identify fake or altered photos, such as those attributed to a specific individual like Vargas, there are several methods and tools you can use:
1. **Reverse Image Search**: Use services like Google Images or TinEye to upload the image and find where else it appears on the internet. This can help you verify its authenticity.
2. **Photo Forensics**: Websites like FotoForensics can analyze an image for signs of manipulation.
