Is it possible to blit images to XMB with OSLib? I know that it is possible with GU, but it seems kind of hard to learn... So if you know something about it, please tell me

Well i just it could be done, but seems impossible. I tried GU, but can't get my image displayed, could you help? The screen just go blank and nothing happens...

Code:
#include <malloc.h>      
#include <pspkernel.h>
#include <pspdisplay.h>
#include <pspdebug.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <pspgu.h>
#include <pspgum.h>
#include <psprtc.h>
#include <png.h>
#include "main.h"            
 
#define BUF_WIDTH (512)
#define SCR_WIDTH (480)
#define SCR_HEIGHT (272)

PSP_MODULE_INFO("Lesson1", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);
PSP_HEAP_SIZE_KB(10000);
 
void *dList;      
void *fbp0;      
 

void InitGU( void )
{
   
   sceGuInit();
        sceGuStart( GU_DIRECT, dList );
   
   sceGuDrawBuffer(GU_PSM_8888,(void*)0,BUF_WIDTH);
   sceGuDispBuffer( SCR_WIDTH, SCR_HEIGHT, (void*)0x88000, BUF_WIDTH);
   sceGuDepthBuffer( (void*)0x110000, BUF_WIDTH);
 
   sceGuOffset( 2048 - (SCR_WIDTH/2), 2048 - (SCR_HEIGHT/2));
   sceGuViewport( 2048, 2048, SCR_WIDTH, SCR_HEIGHT);
   sceGuDepthRange(0xc350,0x2710);

   sceGuEnable( GU_DEPTH_TEST );
   sceGuFrontFace( GU_CW );
   sceGuShadeModel( GU_SMOOTH );
   sceGuEnable( GU_CULL_FACE );
   sceGuEnable( GU_CLIP_PLANES );
        sceGuFinish();
   sceGuSync(0,0);
 
   sceDisplayWaitVblankStart();
   sceGuDisplay(GU_TRUE);
   
}

void SetupProjection( void )
{
   
   sceGumMatrixMode(GU_PROJECTION);
   sceGumLoadIdentity();
   sceGumPerspective( 75.0f, 16.0f/9.0f, 0.5f, 1000.0f);

   sceGumLoadIdentity();
 
   sceGuClearColor( GU_COLOR( 0.0f, 0.0f, 0.0f, 1.0f ) );
   sceGuClearDepth(0);   
}

int main(int argc, char **argv)
{
   pspDebugScreenInit();
   SetupCallbacks();

   sceRtcGetCurrentTick( &fpsTickLast );
   tickResolution = sceRtcGetTickResolution();
 
   dList = memalign( 16, 262144 );
   fbp0  = 0;
 
   InitGU();
   SetupProjection();
 
   Image *img=loadPng("ourImage.png");
   sceKernelDcacheWritebackAll();

   while( 1 )
   {
      if(!img) sceKernelExitGame();
      else{
         sceGuStart(GU_DIRECT,dList);
         drawSprite(0,0,32,32,img,0,0);
         sceGuFinish();
         sceGuSync(0,0);
         fbp0 = sceGuSwapBuffers();
         pspDebugScreenSetOffset( (int)fbp0 );
         }
      sceDisplayWaitVblankStart();

        }
 
   sceGuTerm();         
 
   // Free Memory
   free( dList );
   free( fbp0 );
 
   sceKernelExitGame();   
   return 0;
}



Here is the loadPng() and drawSprite() functions:
