where can i post ?

so i like to collect art, fanart, illustrations and crafts related to a topic ,idea or game .and whenever i want to make an artbook, shirt ,theme party or just to have pictures of scenes and characters when i read i open them up , however my collection is getting out of hand and I'm looking for a place to post them online so i can open up some space in my computer i thought Pinterest would be perfect for this but two days of posting and my account has been suspended i have no idea why and if they don't give me back my account i lost half of my 12 years collection, which brings me to my question where can i post my collection without losing it
