[FEATURE] Add image upload and display support (frontend + backend)

[Inclineed]

💡 What's your idea?

Add an image upload and display feature in the app — allowing users to attach, view, and manage images within their posts or profiles.

🤔 Why would this be useful?

Currently, users can only share text-based content.
Adding image support would make the app much more engaging and interactive — users could share screenshots, photos, or visual references related to their posts.
It also improves collaboration and context in shared content.

🎯 Where should this feature go?

• 🌐 Website (React web client)
• 📱 Mobile app (Flutter mobile client)
• 🔧 Core Protocol (Go - main LIBR logic)
• 🌐 Network Layer (Go - P2P networking)
• 🔗 Smart contracts (Blockchain)
• 📚 Documentation
• 🛠️ Development tools

🖼️ How should it look/work?

Users should be able to:
-Upload an image when creating or editing a post.
-View uploaded images in the post feed or detail view.

For the UI:

-Add an “Upload Image” button in the post creation form.
-Show a small image preview before submitting.
-On the post, display the image below the text content.

🌟 How important is this feature?

• 🔥 Critical - I really need this to use the app
• 🎯 High - This would make the app much better
• 😊 Medium - This would be nice to have
• 🤷 Low - Just a small improvement

📚 Examples

Apps like Reddit, Twitter (X), and Discord allow users to attach images in posts or messages — this makes the content more expressive and engaging.
