Images auto upload + image resize + featured

Hey friends!
i am going to setup my 4 years old domain. i have a bunch of images on it which are dead because it was hosted on other websites which are down. I will now edit posts 1 by 1 & will add new fresh images.

I want to do this task quickly:
Copy images from sources >> paste in my WYSIWYG editor & it should automatically upload all or 1st image to my Media library & also resize images too in some particular fix size i mention in settings. From Media i can set featured image then.
I tried manually saving JPEG to my desktop & then upload to library but its too much time consuming.

Also i have tried “QQWorld Auto Save Images” but its asking for pro.
Tried “Auto Upload Images” but it depends on its mood. it sometimes import images sometimes keep sleeping.
Please tell me any best plugin to do that
