There isn't much to say.  This script seems to get ads from Google. Get image,  hyperlink it.   Also display it.
You should see it in action in chrome or Firefox.  Just use a debugger to step in.
add http debugger to monitor the data.  use  fiddler to see the data sent/received.

I can help out although I'm not a native.  I do have a toefl 109 if that helps. 

No, you understand correctly. This is about as useful as any other file merger. It simple puts one file on the end of the other. Nothing more. Wont run, wont do anything.

There are only two ways malware could be hidden (and executed) in images. Either by feature or by flaw. And by flaw I mean (most of the time?) a buffer overflow vulnerability.

By feature
Code could be executed by a image viewer if the image viewer actually had this as a feature. Not as likely with image files, but there have been nemours examples of other file formats that have allowed things like javascript or VBscript to run as a feature. Pretty sure PDF had this a while back(maybe still?), Microsoft office files had(have?) this and so on.

By flaw
As with any other program, a image viewer can have flaws/bugs. And sometimes those flaws/bugs can be exploited. In most cases we are talking about a buffer overflow exploit. This could allow you to add malicious code to an image that would be executed when viewing the image. There are way too many details to go into here and now so I will not explain further. Know this tho, most image formats have been around for a loooong time and so thousends of people have tried finding these flaws already.

There is a third way,  polyglots. You make a hybrid file of two different languages and send them.  An example would be gifar attacks where the gif file was both a valid gif and jar file.

Real gases as they're called are actual `real` gases.  They exist.  Now,  ideal gases are hypothetical gases created after mathematical models.  It was always known that the mathematical model will be flawed but it is read anyways,  why? Because the actual variables for real gases are really to numerous and unless you wish to do a PHD or need some really error free data, you do not need to read it.
All real life systems can be defined with an equation of the type M + Rf ().
Where M is the mathematical model and RF () is your practical variation. 
Now,  you are taught M because you can grasp it and it doesn't need you to perform any sophisticated experiment beyond your ability to perform.  Once you are adept at it,  you're taught the practical variation that occurs.

A high school student will never need to learn the complex parts, do a PHD if you really want to learn this. 

Sublime has unlimited trial which is why I ruled out any self modifying stuff.
Op, take a look at lena's reversing tutorials if you need good practice.

Definitely PHP. node JS solves the problem for scalability which you do not need for at least a long time,  if ever.

PHP has a lot of stuff already written and you will get all the modules you need over the net.  This way your development time is small and you get to see all aspects of the problem. You'll deliver a quality product in less time, but with old technology.

If this is a learning exercise then I'd say that you use nodejs or python django. These are relatively new with smaller libraries but they'll grow over time and they look promising.  Specially nodejs because of widespread js use.

nice share, but the sandbox will block everything malicious in the pdf reader. I had some malicious pdf from 2008's. they dont execute anymore.
Dunno if the sandbox is broken yet.

A GPU handles calculations better. Yes it is possible to build a computer using only gpu.


also, the term I believe was GPGPU.

this is just a trend in technology. technology always moves this way, a solution, then a compact generalized solution and then again specialized solution.
Technology converges and diverges. I would say that in a few years we will get a computer purely on GPU, that will be the general solution case.
