What I am confused is how to go on with adding the images itself. I have seen some of the existing plugins but none seems to follow a common solution for this. In some one has to upload each image individually (the image being the post type itself), others use the wp file uploader but only one image can get uploaded at a time etc.. The one I like the most is Nivo Slider, which adds the meta_box_upload with the plupload multiple file uploader script.
My question is, which options do I have here? Also, I can't seem to find any good tuts on this either (maybe cause of my lack of experience?). Any hints would be much appreciated.
