Remote image upload is a very interesting thing, such as you copy a file from another site, if the text with a picture, the editor will automatically extract the picture, upload, so do not worry about the remote image after the failure of their own local can not browse.
Through the check, found that the remote Picture Upload action page is: getremoteimage.php. After opening, we first configure the Savepath, because different users need to be stored in a different directory, so as to avoid confu

Just like the fifth question, traverse the images under the given directory and scale the images larger than the iPhone 5 Resolution. Use the Python PIL library to process the image. The iPhone 5 screen resolution is 640 × 1136. Scale the image larger than the resoluti

This usage is appropriate for both the file and the catalogue:
rsync-avh/path/to/myfolder/home/pi/tmp/
rsync Remote Backup
Rsync can also be used for remote backup between different machines, which is similar to the SCP instruction, but rsync is more efficient:
Rsync-avzh/mypath/myfile.gz pi@192.168.1.12:/mybackup/
This will bring the local myfile.gz back to Pi@192.168.1.12 's/mybackup
