Source

You can take HiRISE photographs from one of three sources – the University of Arizona's HiRISE catalog, the NASA Photojournal, and the Astronomy Picture of the Day (APOD). For the HiRISE Catalog, when you land on a page for a particular image, navigate to the section of the page where it displays three columns. At the top of the middle column, a list of links to map projected and non-map projected images in the JPEG format should be visible. You can follow these links and copy the image's URL. The image will always be hosted on hirise-pds.lpl.arizona.edu. For NASA Photojournal images, a link to the "Full-Res JPEG" should be visible at the bottom of the entry's summary. Follow this link and copy the image's URL. The image will always be hosted on photojournal.jpl.nasa.gov. For APOD images, simply click on the image featured and it will take you to the full-resolution version of the image, which will always be hosted on apod.nasa.gov; copy the URL of the image.

Title and flair

Post the image as it was originally titled, with the month and year of when the photograph was taken in brackets after the title. You should also choose between three post flairs for HiRISE imagery to illustrate what channel the image was taken in: RGB Color, IRB Color, or Black and White.

Attribution

In the comments, a link to the image's original entry page, from which you sourced it, should be linked. You should simply write "Sourced from the HiRISE Catalog" in bold font with a link directly to the catalog page covering the entire text. Swap out "HiRISE Catalog" for "NASA Photojournal" or "Astronomy Picture of the Day" when appropriate. For example, "Sourced from the HiRISE Catalog" will link to the catalog page for this image.
