@@ -36,4 +36,4 @@ There are three main reasons this could happen:
 
 - _Invalid image format_: While darktable will attempt to import all supported file extensions, the extension is not a guarantee that darktable will be able to interpret the file's contents. If the file format (or an option within that format, such as compressed mode) is unsupported, darktable will display a question mark ![unsupported](./thumbnails/unsupported.png#icon) in place of the image. If the file appears to be corrupted, darktable will display a warning triangle ![error warning](./thumbnails/corrupt.png#icon) in place of the image.
 
-- _Low memory_: In the rare evant that darktable runs out of memory while generating a thumbnail, it will warn you and display a skull. This can happen if darktable is run with sub-optimal settings, especially on a 32-bit system. See [memory & performance tuning](../../../special-topics/mem-performance.md) for more information.
