Gathering info from this link stackoverflow-image save doesn't work with chmod 777 and from user azerafati and Loek Bergman

if you were to look under /etc/apache/envvars file you will see something like:

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data

Apache is run under the username 'www-data'

'0755' means the file owner can read/write/execute but group and other users cannot write. so in ur terminal, cd to the folder containing your 'images' folder. then type:

find images -type d -exec chmod 0755 {} \;
find images -type f -exec chmod 0755 {} \;
sudo chown -R www-data:www-data images

you must change persmissions first before changing owner. enter your password when prompted. this will make 'www-data' owner of the images folder.

your upload should now work.
