how to create image upload of difference dimensions I am creating a custom gallery. I require images that are the thumb nail and the big image size. I have custom content type. When i add the image field it allows me to enter the dimensions size. Is there a way for drupal to create 2 images. ie thumb and big image
You can either create two image fields, one for the media image and another one for the thumb, or you could just have one and use different Image Styles ( admin/config/media/image-styles in Drupal 7 ) for both the full and thumbnail. You could even add Image Javascript Crop for more fine-grained control of the thumbnail.
