TL;DR

🆕 New

  • Build a whole folder's thumbnails up front from the command line (#23)
  • Build thumbnails here on the right-click menu
  • Welcome screen offers the format badge option (#22)

🔁 Changed

  • Toolbar icons now look the same on every Windows version
Read more: everything in 1.12.0 ### Added - **Build thumbnails for a whole folder up front, instead of waiting for Explorer to catch up.** `st2k prebuild <folder> --recurse` walks a folder and asks Windows for every supported file's thumbnail, so the pictures are already there the first time you open it. Useful after clearing the thumbnail cache, or for a large library you have just copied in. By default it only builds what is missing, so running it twice is cheap; `--rebuild-all` skips that check. It reports how many were built, already present, and failed. Files that live in the cloud and have not been downloaded yet are skipped, because building their thumbnails would pull them down. Requested by @taylor-p-mason (#23). Windows stores thumbnails separately for each icon size, so building only one size would leave you still watching tiles appear in every other Explorer view. It therefore builds the three sizes Explorer's Medium, Large and Extra-large views actually read. `--size` takes a list if you want to choose (for example `--size 256`), and sizes that land in the same internal bucket are merged so nothing is built twice. - **"Build thumbnails here" on the right-click menu for folders and drives.** The pre-build feature above is now a menu entry rather than a command you have to type. Right-click a folder (or the empty space inside one, or a drive) and it walks the whole tree with a progress window you can cancel. It appears by default and can be turned off in Settings. It is a plain menu entry rather than a shell add-in, so it loads no SageThumbs code into Explorer and cannot slow down or crash your folder windows. - **The welcome screen now offers the format badge.** The option that stamps a small label (`PSD`, `SVG`, `AVIF`…) into the corner of a thumbnail already existed in Settings, but nothing pointed at it, so people who wanted a way to tell similar-looking files apart never found it. It is now one of the optional switches on the welcome screen's second page. Still off unless you ask for it, because it changes the picture you asked to see. Raised by @knchmpgn (#22). ### Changed - **The toolbar icons now ship with SageThumbs instead of coming from Windows.** They used to be drawn with whichever icon font the operating system happened to provide, which is why they vanished entirely on Windows 10 (fixed in 1.11.1) and why they looked slightly different between Windows versions. A small icon set is now built into the program itself, so every machine shows the same buttons regardless of Windows version. It adds about 4 KB. The old behaviour is kept as a fallback in case a machine refuses the built-in one.

Portable (no installer)

Extract and run. Nothing is installed, nothing goes in the registry, no admin needed. Settings live in SageThumbs2K.ini next to the exe.

It gives you the app and the command line tool: settings, convert and resize, quick preview, screenshots, OCR, the colour picker and the folder tools. It does not give you Explorer thumbnails or the right-click menu, because Windows only loads a shell extension whose COM class is registered. Install the normal build for those.
