[cipchk]

• close nz-upload can't read cloudimage convert url, this url work with html img tag #5520
• close feat(module:upload): if UploadFile manual set isImageUrl true, skip checkfile #4990

nzPreviewIsImage 可以更好的自定义预览文件URL是否有效的图像格式，特别是一些CDN它们本身没有一个很明确的图像资源标识，比如：

• https://a.com/1.jpg 一种标准图像路径
• https://a.com/key?w=800&force_format=jpg 也算是一个有效的图像路径
