3. Flickr
We are continuing our list of best online photo storage services with Flickr that found its way on our list because it is the perfect online photo storage service for large photos. You can upload and backup your photos without worrying about losing their quality, and the best part is, it has a free version. You can use 1TB of Flickr’s storage; about 2 million photos per account, for free to upload and share your photos. In addition to this, you can also download the Flickr application on your smartphone, and you can upload photos from your phone as well. To organize your account better you can tag your photos, but you cannot change the layout on your profile.
