I hope you can help me. I'm trying to transfer the last year's photo albums from my Ubuntu machine (12.04 LTS) to an iMac (10.8.4). I don't know how can I do that (it's about 45 GB of pictures that I want to share). What do you suggest? My computer does not have Bluetooth neither CD/DVD drive. I tried to upload the files to a cloud storage server but it is sloooooooooow and it would take years.

Any ideas?

Thank you in advance for your cooperation.
