• 直接使用.ico的报错：

execute of template failed: template: _default/list.html:25:44: executing "main" at <$image.resource.Width>: error calling Width: *resources.genericResource is not an image

• 直接在windows上修改文件名后缀后的报错：

execute of template failed: template: _default/list.html:29:52: executing "main" at <$image.resource.Fill>: error calling Fill: image "路径\\example.png": fill : image: unknown format
