+The -n option only simulates the command, so that you can verify the changes. Run without it to actually make the changes.
+The regex ''(.{10}).*(\.jpg)'' consists:
+''.{10}'' - any 10 characters, in a group (…), followed by ''.*'' - any number of any characters followed by ''\.jpg$''
+the extension at the end ''($)'' of the filename, in the second group. The replacement ''$1$2'' is just the first group followed by the second.
