Why Image Options Disappear

1. Different image types carry different options
   • Odoo's built-in default images (from image_library) include metadata (like mime type) that enables extra options (Masonry, width controls, etc.).
   • Once you replace an image with a custom one, that metadata (and associated filters or options) often isn't applied to your new image, so those options disappear. 
2. Large image sizes also matter
   • Using very large images (like 1920px wide) means Odoo scales them down aggressively—often stripping out attributes needed for certain display options. That affects editing features and can hurt SEO.

How to Fix It

• Use properly pre-processed images
  Upload images that already match your target size (e.g., 400–500px width). This helps Odoo preserve options like Masonry and width controls.
• Regenerate the snippet’s metadata
  If you’re comfortable with developer mode, clear and rebuild the image metadata or use the “regenerate assets” feature (in debug mode via the bug icon) to refresh filters.
• Apply community patches if needed
  Check for recent updates: in v17+, default image attachments were moved into an “updatable” file—this restores compatibility after upgrades.
