Show image with variable name Thymeleaf Spring Boot

This video about saving files on file system (in db we saving only file name and file path).
Thank you, author! It's very helpful

Thank you so much for making & sharing this playlist, awesome stuff! There are a few things that are still a bit confusing to me. In a real-world application, would we be uploading to cloud our spring boot app, database (photo meta data) and photos, separately? Is there a use case when we would want to have photos in our project folder? Let's say we are building a social media app and want to view a profile photo we just saved. How would that work, on a high level? Would we need to look up the photo from the cloud (via some URI) in our spring boot app? Thanks!

Oh, i tried it in this way, but i'm getting the exception... Thymeleaf is trying to parse in my relative path to image? Could you give me a hint, please, what can be wrong with this exception? (I have no "/photo/" path, just "/static/") Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NumberFormatException: For input string: "0.jpg"] with root cause
