[steam] How to upload screenshots without using the in-game Steam overlay?

Some games don't work with steam-overlay. You can't Shift + Tab and you can't take screenshots. Basically, this is often the case with indie RPG games. This guide will show you how to upload screenshots for such games, when you can't do it with steam overlay.

Step 0 (Preparation phase)

This assumes that you already have the screenshot manually made. There are many ways to do this. One of which is to use PrtSc (Print Screen) and paste it in the 'Paint'. Then you just save it in ''.jpg'' format.

For Step 6, download ''Notepad++'' program. You can download it by clicking here [notepad-plus-plus.org].
Step 1

1. Find app Id of the game. 

Use steamdb.info. Write the name of the game and see the ''APPID'' part. The number will be there.
Example: ''Counter-Strike'' will have the App Id ''10''.

Step 2

2. Find the path to make the folders.

Find this path

Paste your text hProgram Files\Steam\userdata\X(number may vary)\760\remote.

If you have just one account then you will find the right folder I marked with an ''X'', with ease. But if you have several accounts you need to find the folder that belongs to your account.

For that you could visit steamidfinder.com and paste the URL of your steam profile page.
You will see this box with your info in it:

You need the numbers I marked as ''X'' in ''steamID3''.

It will look like this: steamID3 [U:1:XXXXXXXXX].

Find the folder in ''userdata'' with these numbers and open it.

Remember the path we need:

Program Files\Steam\userdata\X(the folder with account numbers you currently searched for)\760\remote

Go to ''760'' folder and then open ''remote'' folder.
