Open several images and display them without deleting old on

I'm writing a program in C which needs to open several images multiple times. But I need all the images to remain displayed. So I do this:

This is within a for that loops in the number of images I open each time

Quote:

imagen = GTK_IMAGE(gtk_image_new_from_file(MagickGetImageFilename(image_wand)));
gtk_box_pack_end(GTK_BOX(caja_h),GTK_WIDGET(imagen),FALSE,FALSE,1);

gtk_box_pack_end(GTK_BOX(caja_v),caja_h,FALSE,FALSE,1);
caja_h = gtk_hbox_new (TRUE, 0);

The first time I open the images everything works fine but I need to be able to open several groups of images and display them. The second time I open another group of images the first image in the ones already displayed dissapears and only the first one of the second group I opened shows up.

Does someone has any tip on how to do that?

I'm sorry but you really need to post more code for us to be able to tell what happens. When you load an image it does not destroy old ones by default, so the question is not how to do it without deleting but rather why is your code deleting it in the first place (and that cannot be seen from what you have provided -- only guessed at -- possibly because you are overwriting pointers).
Please post more code.

Ok, that gave me some tips. Yeah I was deleting before the for loop!

Code:

  if(imagen != NULL)
  gtk_image_clear(imagen);

Thanks a lot I think that fixed the problem.
