how can i avoid the instgram image copy banned?

Hi, i want to share spam pictures, i have two exemple, and i like to duplicate them, or create bluk of them, and be able to post those two exemple to unlimited times.

i need to bluk that, so photoshop isnt that good option, cuz its take to much time.

i try some duplicate software, but that dosent work, i try even md5 changer, didnt work aswell.
