Will uploaded Image being removed after plugin no longer installed?

Hi, I will be upgrading to paid plans but would probably need this plugin to auto upload images from in my current blog postings to redirect to the new upgraded website. The thing is , this plug in is only for business plan and I cannot afford that on a long term. I am thinking if I will be able to upgrade to business plan, and let this plug in do the auto uploading, and then downgrade my plan after the uploads are completed.

Will down grading my plans affect what the plug in has already done to my images? Or do I have to be paying for the plugin to be installed for as long as I want my images to stay in my posts.
