얼마전에 사진 정리 도구를 Piwigo에서 PhotoPrism으로 변경했습니다. Piwigo는 매우 좋은 어플리케이션이지만, PhotoPrism의 현대적인 느낌과 AI를 이용한 사진 분류기능이 매력적입니다. PhotoPrism은 Golang으로 개발되어 있으며, REST API를 통해 다양한 프로그래밍 언어로 활용할 수 있습니다. (Browse Your Life in Pictures – PhotoPrism). 그러나 여러 예시가 Golang이라 그것을 활용해 보았습니다. Golang은 처음이로 ChatGPT를 이용해서 Library와 Sample을 만들었습니다.
AzureAI를 사용해 태그를 추가하고, Piwigo의 사진을 PhotoPrism에 업로드 하는 것이 골이 었고, AzureAI를 사용한 이유는 일정범위(개인용으로 충분한)에서 무료 사용기 가능하다는 점입니다.

I recently switched my photo organization tool from Piwigo to PhotoPrism. While Piwigo is a very good application, I found PhotoPrism’s modern UI and AI-powered photo capabilities appealing. PhotoPrism is developed in Golang and can be utilized with various languages through its REST API. However, since many examples are in Golang, I decided to use that. As it was my first time using Golang, I wrote libraries and samples with ChatGPT guidance.
Adding tags with Azure AI and uploading photos to PhotoPrims was the goal, and the reason for using Azure AI is that it offers free usage, which is sufficient for personal use.
