I Want to post My Instagram updates to my blog but..

I want to post my instagram photos on my blog but the photos arent in my niche…

i have funny and inspirational photis on instagram but my niche on wordpress is rap music…
i was thinking i could create a sub domain then upload the photis there? i have no idea..
would it be bad for seo if i did? if so why?
