Javascript-question about the combination of my currently rented linux Server (centos64bit) and youpai

I would like to ask my website and App (Android) sharing a linux background, because I have a lot of images on the website, I plan to use upyun as a picture. The problem is: 1. is it true that all of my images can be placed on and shot again, and there will be no images in my linux system ?? 2. because I... I would like to ask my website and App (Android) share a linux backend, and I plan to use upyun as a picture because I have a lot of website images. The problem is that

1. Is it true that all of my images can be placed on and shot again, and there will be no images in my linux system ??

2. this is because the size of my website images is huge or small. I want to ask if your system will automatically generate data when a user attempts to upload images. (See I have to set up another snapshot, but where can I set it ?) In the future, when the system is used, it is used to generate a snapshot slightly, instead of using the original snapshot for further processing.

3. I want to ask if the auto-generated data on the primary node will consume traffic? Which part will be consumed? Internal Storage ??

4. A lot of false settings may take a long square shape (long and long square) when used. But in your system, false settings have a fixed value: Square. How can this happen ?? Take the short answer as the baseline and then make the cut ??

5. It must be cutting, not stretching, and other changes. Can this happen again? What should I do? Can I enable the cutting-edge JavaScript code in upyun?
I guess I should not do that. How can I do this? I have a growth margin and a growth margin, but I want to capture a crop based on the smallest margin (center between top, bottom, and left)
(Just like the pinterest petals of many movie websites)

1. Images are stored on the youpai cloud server, and the domain name for accessing images also contains.upyun.com. CDN acceleration is better than accessing your own server
2. It is unclear whether different versions are automatically generated, but you can set different sizes through parameters during upload.
3. x-gmkerl-typeThe parameter can be set to the smallest edge.fix_minProcess images
