Didn't you just change the default configuration, which is, by definition, configurable anyways?

[qwIvan]

If I doesn't configuration:
/usr/bin/imgur-screenshot: line 504: cd: /home/ivan/Pictures: No such file or directory

~/Pictures is the default XDG_PICTURES_DIR is English, but in Chinese, the path is ~/图片.

See in https://www.freedesktop.org/wiki/Software/xdg-user-dirs/

Sorry, I may have misunderstood this. Your PR title confused me.

Was looking if there was an issue for this. One thing for logs can you confirm there isn't a way to change this?

imgur-screenshot/imgur-screenshot.sh

Line 69 in 3f860be

log_file="${HOME}/.imgur-screenshot.log"

looks hardcoded to me. XDG doesn't really have a standard for this but I think a env variable would be good to have.

Not sure how many more comments to put around the config section 😛

Wow. Was paying attention too much to this ticket and then saw credentials.conf and so I thought it couldn't be in that. Sigh, sorry for that...
