Haha, that's alright. It's just I can't find a piece of code that can do it.

Nothing works.

you make an HTTP request where you receive the pages HTML

then you parse for any and all img tags in it

and then you make an HTTP request on those images whose response you save to the file as a byte array

Um.. hahaha I didn't understand anything there. I am so very new to C++.

Never mind, I just need to find code on how to make a HTTP request.

There is nothing without errors! God damn it!

Simplest way is to use a library like libcurl: https://curl.haxx.se/libcurl/

 

Otherwise you'll have to implement the whole protocol yourself (not worth it).

 

You could also delegate to another program such as wget (exec wget from within your own program).

This is so complex.

It's really not that hard, the example given in this SO thread shows you only need a few lines of code:

http://stackoverflow.com/questions/1636333/download-file-using-libcurl-in-c-c

 

The hardest part for a beginner will be to learn how to include a 3rd party library but this is a skill you will need again and again so spending the time to learn this is worth it.

This will be able to be exported in a singular exe file and run perfectly fine anywhere else when inputted?

Yes, if you make a static build of libcurl. What platform/compiler ?

I'm using Visual Studio.

It's simple. Just scrape the page, parse the html, find the image you are looking for, request the image from the website, scrape the response and store it in a byte array. Save the byte array as a file with ."YourImageTypeHere" after the name in the path string. Since you're using .Net, you can do that all without writing hardly any code using the WebClient class and regex.

Why do you need to do that anyway?
