Getting Started
Images are hosted in the cloud and load automatically — no setup is required. Simply open the HTML file in your browser and start browsing.
Local folder (optional). If you have the image files on your own computer, click Select Images Folder to load them locally. Local files load faster and work offline. The viewer will use local files when available and fall back to the cloud otherwise.
The viewer remembers your local folder between visits. After selecting it once, the button changes to “↩ Re-open “[folder name]” — one click restores it. This requires Chrome or Edge; Firefox users will need to re-select each visit.
Browsing the Table
The table lists every academy and year for which files exist, along with the number of images in that group.
- Search box — type any part of an academy name or year to filter the table in real time.
- Year dropdown — filter to a single year. Works alongside the search box.
- Column headers — click Academy, Year, or Files to sort. Click again to reverse the order.
Opening a Group
Click any row in the table to expand it and see the images for that academy and year. Click the row again to collapse it. Multiple rows can be open at the same time.
Images only load when you expand a row, so the page stays fast even with tens of thousands of files.
Thumbnail vs List View
Use the Thumbnails and List toggle buttons to switch how images are displayed inside an expanded row.
- Thumbnails — a grid of image previews. Best for quickly spotting which images are rotated or identifying content at a glance.
- List — a compact list with a small preview and the full filename. Best for finding specific files by name.
Viewing a Full-Size Image
Click any thumbnail or filename to open the image in the lightbox viewer, which overlays the page.
- Use the Prev and Next buttons to move through all images in the group without closing the viewer.
- Click the dark background or Close to return to the table.
Keyboard shortcuts (when the lightbox is open):
- ← → — previous / next image
- R — rotate clockwise 90°
- L — rotate counter-clockwise 90°
- + / - — zoom in / out
- 0 — reset zoom to fit
- Esc — close the lightbox
Zooming — scroll the mouse wheel to zoom in and out, or use the + / − buttons in the control bar. Click the image to zoom in; click again to reset. When zoomed in, drag the image to pan around it.
Rotating Images
Some microfilm scans were filmed sideways and need to be rotated to read correctly.
Rotate a single image — hover over a thumbnail to reveal ↺ / ↻ buttons, or use the ↺ CCW / ↻ CW buttons in the lightbox (L / R keys also work).
Rotate a whole group at once — use the ↺ All / ↻ All buttons in the lightbox to rotate every image in the current group in one click.
Rotate a custom selection — in thumbnail view, select images first, then use the toolbar that appears above the group:
- Ctrl + click (or Cmd on Mac) — toggle individual images in or out of the selection
- Shift + click — select a range from the last clicked image to this one
- Select All — selects every image in the group
- Deselect All — clears the selection
- ↺ Rotate Selected Left / ↻ Rotate Selected Right — rotates only the selected images
Rotations are saved instantly to your browser and persist across sessions. A future update will let you export and permanently apply them to the image files.
Tips for Large Folders
- The initial folder scan is done by Windows, not the browser — it may take 10–30 seconds before the loading progress begins.
- Images load lazily — only when you expand a row — so browsing the table is always fast regardless of how many files are in the folder.
- If the browser seems unresponsive immediately after selecting the folder, it is processing file references in the background. The counter in the status bar will update as it progresses.
