'72850' in my example pictures) to the 'new' 'screenshots.vdf' AT THE END OF THE ENTRIES FOR THAT SPECIFIC GAME. To do this, first copy the entries from the 'old' 'screenshots.vdf' file for a specific game ID (i.e. You will need to copy/paste each individual game's screenshot entries one at a time. The second file 'screenshots.vdf' is a bit more complex, because it lists the screenshots first by the Steam ID of the game, and then by an arbitrary numerical order. See pictures 'Steam 01' and 'Steam 02' for an example. Copy the data below the '760' from the 'remotecache.vdf' file in your old directory and paste it into the bottom of the 'remotecache.vdf' file in your new directory, MAKING SURE NOT TO CAUSE ANY SYNTAX ERRORS FROM EXTRA OR MISSING BRACKETS. Open up 'remotecache.vdf' using a basic text editor (I recommend Notepad++). You will have to manually sync these two files by amending the entries from the files in the 'new' screenshots directory with '>'ones from the 'old' screenshots directory.

In addition two the 'remote' folder there will be two '.vdf' files in the '760'Дirectory, 'remotecache.vdf' and 'screenshots.vdf'. : MAKE A BACKUP OF BOTH STEAM '760' DIRECTORIES BEFORE YOU BEGIN IN CASE YOU MAKE A MISTAKE!!! Additionally you can use the method above to to 'merge' two out of synch Steam directories, or amend your current screenshots directory with an old Steam installation or other computer's screenshots and combine both screenshot directories with some additional steps: The method above worked very well, but I have an additional note and a correction to the command syntax:
