This script can be used to download images from reddit posts.

Dependencies (all installable by pip)

beatifulsoup4
praw
progressbar
The other imports should be installed by default.

Usage

You can for example download wallpapers from /r/wallpapers.

usage: reddit_dl.py [-h] [--count COUNT] [--output OUTPUT]
                    [--category {top,top-all,top-day,top-hour,top-month,top-month,top-week,top-year,con,con-all,con-day,con-hour,con-month,con-week,con-year,hot,new,new-bydate,new-byrising,random,rising}]
                    subreddit

Example:

./reddit_dl.py --output ~/wallpapers --count 10 --category top-all wallpapers

Is there any way to contact you privately? This script returns error when I try to run it.

Just ask here, so others can benefit from a solution. What's the error message?

Edit: So I just tested the script and it still works fine for me. Make sure you follow the steps from the first comment (install all the dependencies). In case you are using python3 instead of python2, I just added a new script for that (The dependencies of the python3 script are descriped in the code comment)
