### 2.3. Images

You also have to manage screenshots. Here are some hints for making good screenshots:

- reduce screenshot area as much as possible cropping the window manager borders and disabling the help button (you can do it in the preference dialog),

- set the image mode to indexed 255 colors Image → Mode → Indexed

  This is not necessary for icons and if your image has only few colors. In these cases, indexed images are bigger than non-indexed.

- set print resolution to 144 ppi (not for small images like icons). You can do this easily with GIMP from Image → Print Size...

- Export images in the PNG format.

Don't include English text in images. Translators can't translate it and many users don't like that. Use XML captions instead, or provide a .xcf file in the Docs → xcf images folder, indicating it by a comment in the XML file:

Icons for GIMP are in usr/share/gimp/2.0/icons. GTK icons are in usr/share/gtk-doc/html/gtk2.

To include an icon in the text:

Three commands to manage your images:

- make check-image-resolutions-en: gives the references of images whose resolution is not 144 ppi.

- make check-images-en: give references of missing or orphaned images.

- mogrify units PixelsPerTrack -density 144x144 *.png to set the print resolution of all PNG images.
