感谢您对问题的详细描述。

我已在本地重现了该问题，我认为这个拉取请求应该能解决您所描述的问题。

`UploadCreator` counts the number of pixels in an file to determine if it is val…id. `pixels` is calculated by multiplying the width and height of the image, as determined by FastImage. SVG files can have their width/height expressed in a variety of different units of measurement. For example, ‘px’, ‘in’, ‘cm’, ‘mm’, ‘pt’, ‘pc’, etc are all valid within SVG files. If an image has a width of `0.5in`, FastImage may interpret this as being a width of `0`, meaning it will report the `size` as being `0`. However, we don’t need to concern ourselves with the number of ‘pixels’ in a SVG files, as that is irrelevant for this file format, so we can skip over the check for `pixels == 0` when processing this file type.

编辑：奇怪……测试在我本地通过了，但在我推送后却失败了。我明天会深入调查这个问题。
