Phosor
Internal Beta

Browsing Photos

Beta Status

Phosor is currently in an Internal Beta stage. Features may change before the public release. Performance may occasionally be inconsistent depending on hardware, image formats, and library size. Unexpected bugs may still occur. Feedback from beta testers is highly appreciated.

Phosor displays photos one at a time in the main viewing area with fast loading and smooth navigation. This page covers how to navigate, what to expect during browsing, and current limitations.

After scanning, the first photo appears in the main viewer. You can navigate using the keyboard or on-screen controls.

Action Input
Next photo → (right arrow) or on-screen chevron button
Previous photo ← (left arrow)
Wrap-around Pressing → on the last photo returns to the first

Wrap-around navigation

Navigation wraps around in both directions. Pressing ← on the first photo takes you to the last, and vice versa. This allows continuous sorting without reaching a dead end.

Preview Loading Behavior

  • Photos appear quickly after loading.
  • Frequently viewed images reopen instantly.
  • Navigation remains responsive even during rapid key presses.
  • Adjacent photos are preloaded in the background to reduce waiting.

Prefetch

Phosor automatically preloads the next and previous photos in the background after displaying the current one. Backward navigation is just as fast as forward navigation.

For more details on how previews are generated, see Preview Engine.

What to Expect

  • Each photo resets zoom and pan to default (50% zoom, centered).
  • The filename and format extension appear in the footer bar.
  • If an image fails to load, the viewer returns to a valid empty state.
  • Rapid navigation does not cause flickering or stale image display.

Color-coded flag indicator

The small colored square in the footer (next to the filename) reflects the current photo's assigned category color. A gray indicator means the photo is unflagged. See Categories for more.

Sort Progress Counter

The footer sidebar shows a live counter tracking how many photos have been sorted out of the total. For example: 15 / 200 (7%).

Current Limitations

  • Very large JPEG files may cause memory spikes.
  • Zoom and pan reset on each photo change (by design — see Known Issues).

Large JPEG files

Very large JPEG files may cause memory spikes. See Performance for details.
