I uploaded an image, but can I upload it again as a vector ai file?

[? ??]

I uploaded an image, but can I upload it again as a vector ai file?
1. Is it a violation if I upload the same picture as both jpg and vector ai?

2. When I click on the image purchase on the site, there are jpg, eps, ai, etc., so how do I upload them together?

3. On some sites, if you upload a jpg and receive the code to upload a vector, the jpg and vector are bundled together. Is there no such function?

4. Thank you for your answer.
