Hi. So basicly I need assistance with finding out how to externally load mods from a folder, kinda like this:

W/ Image:
  1) Locate all image names in folder.
  2) Add all images in folder.
W/ Object creation code:
  1) Locate all text files in folder.
  2) Import and execute all files in folder.
  3) Change newobject_1 to the user specified name.

I am also Not sure how to set up the object code file, but I assume that this method would work:

MAIN_MyObject.txt (the code that is executed by the game) code:

global.MyObject=object_add()
global.MyObject.createeventfile='CREATE_MyObject.moc'
global.MyObject.keyboardAeventfile='KEYA_MyObject.txt'

And so on

CREATE_MyObject.moc (Create event, loaded by MAIN_MyObject.txt):

global.MyObject.MyVariable=12345

And so on

KEYA_MyObject.txt (Keybaord 'A' event, loaded by MAIN_MyObject.txt):

global.MyObject.x-=3

And so on

So any ideas welcome, please help!

As for the objects, GML has functions like
object_event_add(ind,evtype,evnumb,codestr)
Note that codestr is a string that you read from external files.

I just might be able to help with something like this... I won't do everything for you. However I'll give you a way of finding al files in a folder then loading them into the game.

Find all files script:

Spoiler

var fname , find , directory;
directory = argument0; //not including the final backslash: \
ext = argument1;
fname = file_find_first( string( directory ) + "\*" + string( ext ) , 0 );
global.file_found = "";
global.file_max = 0;

if ( find = 0 and fname = "" ) { exit; }

while( fname != "" ) {
   fname = file_find_next( );
   global.file_found[ find ] = string( fname );
   find += 1;
}

file_find_close();

if ( find > 0 and fname = "" ) {
   global.file_max = find;
   return true; //finished finding files...
} else {
   return false; //still finding files...
}

So to execute this script you would use for example:

finished = script_name( working_directory , ".moc" );

What this script will then return is whether or not the script is finished.
AND it will allow you to access the files via variable:

global.file_found[ position ] //position being 0 - global.file_max;

// and the max amount of files in the array with:

global.file_max;

Now to load the code in the mod files....
you are going to use something similar to this.

File execute script:

Spoiler

var timer , delay , pos;
delay = argument0;
if ( timer < delay ) {
   timer += 1;
}

if ( timer >= delay and pos < global.file_max) {
   execute_file(global.file_found[ pos ] );
   pos += 1;
   timer = 0;
}

if ( pos >= global.file_max ) {
   return true; //finished finding files...
} else {
   return false; //still finding files...
}

What this script will then return is whether or not the script is finished.
So to execute this script you would use for example:

finished = script_name( delay amount );
//delay amount being the time between each execution of code...

I hope this helps! (I am confident that this works, however I did not personally test it, I just typed it )
