What is mirage?

Mirage is a simple, fast image viewer built for GTK environments, originally developed as a lightweight alternative to heavier graphics tools. It has been actively maintained for years and is available in major distributions like Debian, Fedora, and Ubuntu, showing consistent updates and stability.

It's ideal for users who want a no-frills viewer to open and browse image files quickly, without editing features or library management. If you're used to Windows Photo Viewer, Mirage offers a similar experience: open an image, view it, navigate folders, and close.

Compared to Windows Photo Viewer, Mirage feels familiar but more customizable. It supports more image formats out of the box and includes basic navigation shortcuts. It lacks touch gestures or advanced metadata display, but it starts faster and uses fewer system resources.

Best for: Quick viewing of image files without bloat or delays.

Key features of mirage

• Supports common image formats (JPEG, PNG, GIF, BMP, TIFF)
• Simple fullscreen and zoom controls
• Image navigation with keyboard or mouse
• Slideshow mode with customizable delay
• Basic EXIF data display
• Lightweight and fast startup

Tips for Windows users

If you're coming from Windows Photo Viewer, expect similar keyboard shortcuts: arrow keys to navigate, Space to advance, F for fullscreen. Mirage opens most formats without extra codecs. Since it doesn't manage a library, you’ll open images directly from the file manager. Use the command line to batch open or create aliases for frequent folders.
