In "Ugoira", you can set the display time (frame time) for each illustration submitted.
Because it is possible to move PNG and JPEG format illustrations, you can submit illustrations with even richer color and higher image quality than the conventional animated GIF. It is also possible to play or pause the illustration which is not possible in animated GIF images.
Setting the display time allows you to view the illustrations just like an animation.
(* It is necessary to align horizontal and vertical sizes and format the image (extension).)
If you want to submit multiple sheets, a maximum of 150 sheets can be submitted. The maximum size allowed for each sheet is 8 MB and the total for the submission is 30 MB.
In case of animated GIF, contents with maximum size of 8 MB and up to 500 frames can be submitted.
