Main Technical Content: I. Requirements for Uploading Images: 1. Image Format: - The uploaded images should be one of the following types: comic strips, four-panel comics, story comics, or picture books. The recommended formats are JPG or PNG. 2. Image Dimensions: - The size of each uploaded image should not be too large or too small. The recommended dimensions are: - Single image length: ≤16,000 pixels; - Single image width: ≤16,000 pixels; - Horizontal cover image dimensions (750–1,500)*(424–848) pixels; - Vertical cover image dimensions (420–840)*(570–1,140) pixels; - Chapter cover dimensions: 1,600*1,200 pixels.
