    + This option controls the automatic generation of thumbnails for images + and PDF/Postscript files. To make this working, one has to install + the ImageMagick package.

A value of + 300> converts all pictures to thumbnails 300 + pixels wide if they are larger than 300 pixels initially, and leaves + them untouched if they are smaller. A value of 10% + converts all pictures to 10% of their original size. +
