When posting pictures to PW I upload them to a gallery on PW, and then link to them there. It seems there is nowhere here to upload them to (is that correct?) so it seems I am going to need to find somewhere. I am wondering if anyone has any recommendations? Possibilities that come to mind include Google Drive, Dropbox, Flickr, Imgur, ... I want somewhere that is free, and where the operation is easy. I will be very grateful for suggestions.
