How to load 55 Images into 10 pictureBoxs ?

Hi
Could someone tell me how to do some kind of photo album in windows forms?
I have 55 images stored in resource file, and on my Form I have 10 pictureBoxes. I need to load these images into 10 picturesBoxes, but it must be done one by one I mean when I click for example on some button I want to see first 10 images next time when I click button next 10 images should be loaded into picturesBoxes and so on.

I know how to get images from resource file, but I have no idea how to handle swapping images. Moreover, I think there will be a problem with the five last images since it is 10 pictureBoxes on my form.

Does anyone have an idea how to do it?
I will appreciate any pointers.

Thanks

Are you making a thumb nail kind of thing?
if yes try this approach

About the question of 10 loading at a time..
When you have last last 5.
Place them in first 5 and leave the last 5 blank. Or put a gerneal purpose image on them

only a small idea:

1. search all pictures in your directory and store their names in a list or array
2. remember the index of the first picture currently to show (in this initial case 0)
3. fill the picturebox with the first ten pictures found in your array
-> so you have ten pictures shown

4. to let the user navigate through your pictures provide a previous- and a next-button
-> if someone pushes next place your index + X (10?) if there are still enough images left to be shown
-> if someone pushes prev place your index - X as long as it is >0

i do not know, if this idea would solve your problem? which coding-language do you like to use?

a - sorry. probably c# ;).

IList lstPictures = new ArrayList();
int   iIdx           = 0;

private void fillListWithPictures(
         ref IList p_lstPictures,             //our picturelist to be filled
         string    p_sPath)                   //path where images can be found
{
          try {
                //Control if there is a directory
                if (Directory.Exists(p_sPath)) {

                    DirectoryInfo di = new DirectoryInfo(p_sPath);
                    FileInfo[] rgFiles = di.GetFiles("*.jpg");
                    foreach(FileInfo fi in rgFiles) {
                        p_lstPictures.Add(fi.Name);
                    }
                }
            }
            catch (Exception) {}

} //fillListWithPictures


private void fillPictureBoxes(
         IList p_lstPictures,             //our picturelist
         int   p_iIndex)                   //index of first image in list to be shown
{
         try {
               for(int i=0; i < 10; i++) {

                    //Get picturefilename from list at i
                    //Add it to the picturebox corresponding to index i
                }
         }
         catch(Exception) {}
} //fillPictureBoxes


private void moveNext(
         IList      p_lstPictures,             //our picturelist
         ref int   p_iIndex)                   //index of first image in list to be shown
{

}


private void movePred(
         IList      p_lstPictures,             //our picturelist
         ref int   p_iIndex)                   //index of first image in list to be shown
{

}
