Welcome to r/hirise!
A subreddit dedicated to the most awesome camera ever launched into space, best viewed in the new reddit desktop!
The High Resolution Imaging Science Experiment (HiRISE) is a high-quality photographic instrument mounted onto the Mars Reconnaissance Orbiter spacecraft, launched by NASA in August 2005 and arriving at Mars in March 2006. For the past decade, HiRISE, from the comfort of Low Mars Orbit, has been capturing the many wonderful sights of our alien neighbor in unprecedented high resolution. This subreddit is dedicated to sharing those images in all their glory!

How to post images to r/hirise!
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. If you have any unanswered questions about the image posting process, be sure to ask in the comments below!

HiRISE poster I just made. What do you guys think? Should I add in more slices? Do something different with the type?

Where exactly on the HiRISE site are you guys finding these particular images to post here?
I've poked around their site and can't seem to find where you guys are getting what is posted here.

I like this stuff. We have a large format color printer here at work. I think I'm going to download a bunch of these strips and make a NASA:HIRISE poster or something.
You guys think that would be cool? I downloaded one strip and put it in Photoshop to see it's actual size at 300 dpi, and it ended up being a little over an inch wide and 33" tall. Our large format machine is 36" wide so I could do a 24x36 poster and have around 22 strips going across the poster at 36" tall (enlarging slightly to go from 33" to 36") and then do some NASA:HIRISE type in the middle or something.
