When the user needs to display one thumbnail in the thumbnail list area again, the display end device captures first operation information of the user through the input device, wherein the first operation information comprises modes of double clicking, single clicking, sliding and the like, and a target thumbnail is selected from the thumbnail list according to a first operation instruction, and then the display end device determines the displayed image and the target thumbnail in the image display area as a target image.
When the number of displayed pictures in the picture display area is 1, it means that the picture display area displays only one picture, and the displayed picture and the target thumbnail are determined as target pictures at this time; further, when the number of displayed pictures in the picture display area is greater than or equal to 2, a target display picture is determined from the displayed pictures in the picture display area, and the target display picture and the target thumbnail are determined as target pictures.
When the number of displayed pictures in the picture display area is 2, all the displayed pictures may be taken as target display pictures, or one of them may be selected as target display pictures. For example, assume that the displayed images in the image display area are respectively designated as image 1 and image 2, at this time, after selecting the target thumbnail, the user is prompted to select from image 1 and image 2, and if the user selects image 1 as the target display image, the image 1 and the target thumbnail are determined as the target images. Also by way of example, assuming that the already displayed pictures in the picture display area are respectively designated as picture 1 and picture 2, and that the display time of picture 1 is earlier than the display time of picture 2, then after the target thumbnail is selected, the target thumbnail may overlay picture 1, and thus picture 2 and the target thumbnail are taken as target pictures.
