I had my son's iPhone backing up photos automatically to Google Photos and he ran out of space. I now have his phone backing up to Dropbox where I have a lot more storage. I'm trying to port much of his photo library over from Google Photos to Dropbox photos. I have not found a more reliable way to do this than to download groups of files from Google Photos, and then to upload them to Dropbox, all through the browser (Chrome on a Mac). When I do this, some files are uploaded and organized by the original date as expected (HEIC, MOV, MP4) ; some other very common formats (PNG, JPG) are not organized as expected, they just are dumped in as if they were brand new images. I have confirmed that the original taken date in these files is still present in the EXIF data after I've downloaded them. Is there a way I can get Dropbox to respect the original date of each image when I upload them?
