i finally chose to use Lightroom and imported all my Photos. Problem was that i wasn't able to upload all of them. so i ended up just having of them syncronised. They were visible in the online view but with the note that they need to be uploaded from my pc. Unfortunatly my pc killed his windows installation and so i needed to set it up new. I had my photos on another harddrive, but how can i force LRCC to start uploading the unsynced files? Is this even possible or do i need to delete all Files online and import them again? I hope it's possible bypassing this method, because the fileestructure created by LR is not userfriendly when you have to reimport all images.
