- To be done...
- Select your files in Konqueror then right click on the selected files.
To select multiple files you can left click and drag your mouse. This will create a selection rectangle that selects everything within it. You can also press the control ("ctrl") key on your keyboard while you left click on the files you want.
- Find the "resize image..." option in the context menu (In the action submenu in recent KDE versions).
- Choose your size and select next. If you wish to overwrite the original file don't forget to check the checkbox.
- Check that there was no error and click "finish" to leave the program.
