Every thumbnail image I have looked at on any website (such as tumblr) is uploaded to my PC when I upload images from my gallery. So I'll plug the phone in, choose to upload pictures, it will initially tell me for example "15 images found" but then it uploads like 200 because it's not just uploading pictures, but the thumbnail view of every image from every website I've visited since the last time I uploaded.
How do I get it to upload ONLY the images from my gallery? In particular, only the new images?
Is there a way to not save the thumbnail images to my phone in the first place? I don't want or need them, and I have hundreds of thumbnail photos on my computer now that I neither want or need, and of course they are all mixed in with the photos I DO want.
