I. When the resolution is constant, larger image sizes can accommodate more information, resulting in richer details in the final image. If the image size is set to be small, the image content may appear rough.
II. Although selecting a larger image size can enhance the richness of details, it also increases computational burden, prolongs the time required for drawing, and raises computational resource consumption. Additionally, when the image size exceeds a certain range, the model interprets it as multiple images stitched together, resulting in issues such as multiple people or limbs appearing within one image.
