MacBook Pro saved Picasso and handbrake to desktop and looks like they are there own drive

[knotsure]

I installed the Picasso app from its website and my MacBook Pro saved the program to the desktop as an external drive. When I open the finder it shows as a drive and shows the reject button. I am not sure why it did this, but it has now actually saved the program to the laptop now and is not just shown as a drive. But handbrake is doing this now.
I am a little paranoid right now because I just swapped the hdd for an ssd and am afraid I did something wrong.
I installed Yosemite in an external drive and started the laptop from there. I replaced the hdd for the ssd and then performed a fresh OS X install saved to the ssd. I restarted the laptop and removed the external drive. Everything looks and seems very fast.

This is my first MacBook and I am not very familiar.
So I am still looking around at settings and stuff but if you have any thoughts on the matter I would appreciate it.

It is a 2012 MacBook Pro i7 8gb ram Yosemite OS X .

Those external drives are just the install for the app. If you double click it will either install the app or it will open up and you can drag and drop the app into your applications folder which is the case for Handbrake.
After installing you can eject those "drives/disk images or drag them to the trash.

Those are the disk images... you opened them and installed the programs right? And the apps will open and run? You can safely eject the disk images... and delete them from downloads on your mac if you wish.
