Interactive Java Tool for JSON Editing -- 2

I'm looking for a Java developer who can create a tool that reads data from a JSON file containing both text and images. The program should display the data in a test format, and allow for real-time editing via a drag-and-drop interface. An image replacement button should be included, with support for JPEG, PNG, and GIF formats. Once edits are made, the tool should save these changes in real time and generate a new JSON file.

Ideal Skills:
- Proficient in Java programming
- Experience with JSON manipulation
- Knowledgeable in creating user-friendly drag-and-drop interfaces
- Familiar with various image formats

Please note, the main goal of this project is to provide a seamless, interactive editing experience, so attention to detail and a focus on user experience are crucial.
