Instagram pictures being automatically deleted?

[Mr.Skepitcal]

I had pictures of me and my girlfriend in city centre and another of valentines gifts, for a long time. Now recently they have been somewhat deleted with no notice whatsoever from Instagram and I'm pretty sure nobody knows my password, as I just about remembered it.

If somebody flags a normal picture, can it be taken down with no notice?

if somebody report it violating guidelines they will down it
