Root Cause

上传的文件不是有效的图片格式或已损坏

generic

中文

ImageField验证失败，文件内容不符合图片格式要求

Workarounds

  1. 95% success 
    使用PIL库验证图片：from PIL import Image; Image.open(file).verify()
  2. 85% success 
    model字段改为FileField(upload_to='uploads/')

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Django检查文件内容而非扩展名

  2. 60% fail

    只影响内存使用，不影响文件验证
