Blank Pictures when sharing photos in IG stories and Linkedin

It’s been my problem for a month. I am an iPhone user since iPhone 4 was released that’s why most of my saved photos on my mobile was calibrated on iPhone picture size. I decided to switch this year to Samsung, I bought S9 last March. I don’t know if upgrading OS affected my photos. It’s okay if you’re gonna view it on gallery and share but you can’t do a ThrowbackThursday or FlashbackFriday on your IG stories because every time I’m trying, my photos from iPhone can’t be seen (blank tiles). It bothers me yesterday when I was about to share a picture on LinkedIn, It has a same scenario. Hopefully someone can help me to address this before I reset my phone, which gonna be a hassle.
