Image Picker Debugging Instructions

Test Steps:

1. Go to: Homepage Editor
2. Click on any existing section's "Edit" button
3. Scroll down to "Section Image"
4. Click "Select/Upload Image" button
5. Open Browser Developer Console (F12)
6. Watch for console logs that will show:
   • "Opening image picker. Mode: single Callback: function"
   • "Modal opened successfully"
   • When you click an image: "Toggle selection for: [URL] Mode: single"
   • When you click "Select Images": "Confirm selection clicked. Selected images: [array]"
   • After callback: "Image selection successful!"

What Was Fixed:

• ✅ Fixed ID attribute on hidden ImageUrl field
• ✅ Fixed case mismatch in SelectedImageUrl field
• ✅ Changed onclick inline handlers to event listeners (prevents URL escaping issues)
• ✅ Added comprehensive console logging for debugging
• ✅ Added error handling with try-catch blocks
• ✅ Added validation checks for all DOM elements
• ✅ Added user-friendly error alerts

Expected Behavior:

When you select an image and click "Select Images (1)":

• The modal should close
• The image preview should appear below the button
• The SelectedImageUrl hidden field should contain the image URL
• When you submit the form, the image should be saved to the section

If Issues Persist:

Check the browser console for error messages. Common issues:

• Red error about "callback function not found" - refresh the page
• No images loading - check /admin/upload/list endpoint
• Modal not opening - Bootstrap JS not loaded properly
