Arena Tracker will need to download all Hearthstone card images onto Hearthstone Cards dir. This is done in the background while you use it. You don't need to wait, start your draft or your next game, AT will know what to do.
On Windows and Mac: Arena Tracker setup is done automatically unless you didn't install Hearthstone in its default dir. In that case the first time you run Arena Tracker you will be asked for several dir/files. Check this.
On Linux: Arena Tracker will try to find Hearthstone dir automatically using the command find (Only your HOME dir will be searched). This process can take several minutes, I suggest you to empty your trash bin before, to make it short. If it doesn't success it will ask you to find some dir/files, check this.
If AT doesn't react to what you do in HS, you can try to manually configure HS log like this.
If you have problems installing it or using it I'm happy to help you on reddit.

Thanks to all these projects ArenaTracker is possible.
