The picture format is jpg/jpeg/png

The picture quality requirements are no psoriasis, no text, no watermark, no splicing, no deformation and stretching, etc.

For the picture background, it is recommended to upload a real picture (not a pure white background, no cutout, and the background elements should not be too fancy, etc.)

For product display, it is recommended to upload a real-life model picture, or a full-view product picture; the main body of the product must be clearly displayed, not a hanger or a prosthetic model
