Dynamic picture previewing method and device and emoji package displaying method and device

The invention provides a dynamic picture previewing method. A dynamic picture comprises multiple frames of static image data. The method includes the steps of extracting at least one frame of static image data with a designated frame number from the dynamic picture, and displaying the extracted static image data. By means of the technical scheme, the previewed picture does not need to be downloaded when the dynamic picture is previewed; when the method is applied to an emoji package, the size of an emoji package installation file can be reduced, and network flow is saved; the workload of emoji package manufacturing personnel can be reduced, and the emoji package manufacturing efficiency is improved.
