Although Flickr itself doesn’t support you to sync/backup/transfer Flickr Photos to another Flickr account without switching, another free web app can realize it easily. MultCloud can not only help you transfer Flickr photos to another account, but also enables you to transfer files from one cloud to another cloud just from one single interface in the browser. There have been more than 20 clouds supported.
After signing in or experience without signing up, all you need to do is adding your multiple Flickr accounts in use then you’re able to move/transfer files by directly dragging or using copy options from contextmenu or set under “Transfer” tab.
*Update: MultCloud added a special Cloud Sync service now, you can use it to do sync cloud drive task directly. MultCloud provides 8 normal sync ways.
