I don't think this is a fltk problem - AFAIK there is nothing in the
fltk code that is sensitive to image size (well, at least until you run
out of RAM, anyway...)
So I'd have to guess that something else is awry in your code.
You seem to be using a number of other libraries and frameworks in your
code. Perhaps one of those has a limit?

Well, attached below is a simple example of loading an image in fltk.
I have tested this on WinXP with various jpg and png images up to about
1MB without any problems.
------------------------
//
// fltk-config --use-images --compile scroll-test.cxx
//
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Scroll.H>
#include <FL/Fl_Box.H>
#include <FL/Fl_Shared_Image.H>
#include <stdio.h>
int main(int argc, char **argv) {
if(argc < 2) {
puts("Filename?");
return -1;
}
fl_register_images();
// load an image
Fl_Shared_Image *picture;
picture->get(argv[1]);
// Create the windows and widgets
Fl_Double_Window win(150, 150);
win.begin();
Fl_Scroll scroll(10, 10, win.w() - 20, win.h() - 20);
scroll.begin();
// get the loaded image
Fl_Image *image = (Fl_Image*)picture->images()[0];
// assign image to the display box
Fl_Box *img_box = new Fl_Box(0, 0, image->w(), image->h());
img_box->image(image);
scroll.end();
win.end();
win.resizable(scroll);
win.show();
return Fl::run();
}
