Screenshot suggestions

Please put suggestions for screenshots to go onto the main website on this page. You can post URLs or upload images directly to the wiki.

Here is the new work-in-progress screenshots page:

• http://grass.itc.it/screenshots/

Note that all screenshots are to be licensed under the Creative Commons Attribution ShareAlike 2.5 License. Please leave your name as well so we can attribute correct credit.

• See here for help making an image on this page an instant thumbnail.
  (The syntax is [[Image:{name}|{width}px]])

• PNG images are lossless but can be very large for satellite images & photographs. Best format to use for things like menus with a lot of solid colors and where crispness counts.
  • To help save bandwidth, save your PNGs with compression setting of 9. Often you can reduce the file size significantly by reducing the pallet size to be big enough to hold just the colors used.
  • Running a program like pngcrush can compress it further.

• JPG images are lossy but can be much smaller for things like satellite images & photographs.
  • For quality save nearer to 85%, for size save nearer to 75%.
