No Transparency of Image Indesign

[Diamonds5F8E]

I have Adobe Indesign files which include linked images from other source. In other words the files are sent by email to me from another computer to me. 

I have trouble with these images. Images are No transparent when I export to pdf file. The background of the image is wite. I have tried the followings but don't work-

1. turn transparent ratio to 100 %

2. use Rantangle tool next to the image

3. Linked images cannot update original files are deleted

Therefore please let me know how to solve the issue. Thank you very much.

Yes. Original files are deleted. So I would like to know there is any way to make transparent images.
