Recently I wanted to copy several images from my PC to my blackberr.
Since the blackberry's screen has 320x240, it doesn't make sense to copy the images in full size due to memory space and the time it takes to show each image.
I found a good utility to do this for me, without having to open one by one the images with GIMP.
We run the following command (it may be necessary to restart the session after the installation):
sudo apt-get install nautilus-image-converter
After this, you can select multiple images and with secondary button the following choices appear: 'Resize images' and 'Rotate images'.
A friend also suggested me to see a nautilus script found here: http://www.creationgif.com/debian/nis/
Since the previous functions pretty well, I didn't install the script. If anyone installs it, please tell me how it goes.
