How to view Gmod screenshots from other computer but the same account?

I have an ancient s775/DDR2 system (replaced with AM3/DDR3 pc), but it has some problems with cooling and I can't turn it on, I don't have much time to solve the problem tho. So, I made a big amount of screenshots on it in gmod, but I can't view them on my new pc (yeah I could just take out the hard drive from the old one and connect it to my new system, but the problem is that my psu has only 1 sata power cable (it had another cable, but got fried by optical drive)). Is there some cloud system thing in Steam that syncs not only addons, but also the screenshots? P.S. Both systems have the same account logged in Steam.

Solution 1:

The short answer, Steam does not have the Screenshots. Unless you've uploaded them to your profile in which case they'd be here, under Screenshots

If they aren't there , the only place you'll find them is the HDD you saved them to
