Before uploading the images you need for Image Sets to Dynamic Media Classic, make sure that the images are the right size and format.
To create a multiple-view Image Set, you need images that show an item from different points of view or show different aspects of the same item. The goal is to highlight the important features of an item so viewers have a complete picture of what it looks like or does.
Because users can zoom images in Image Sets, make sure that the images are at least 2000 pixels in the largest dimension. Dynamic Media Classic supports many image file formats, but lossless TIFF, PNG, and EPS images are recommended.
