Thank you for uploading some images! Did you know that Wikimedia Commons recommends the SVG (Scalable Vector Graphics) format for certain types of images? Scalable Vector Graphics are designed to look appropriate at any scale, and SVG images are easier to modify and translate, helping Wikimedia to distribute knowledge to all of the world. A lot of modern programs support SVG export. If you encountered problems or have questions, don't hesitate to ask me, a member of the Graphic Lab, or the Graphics village pump. Uploading images in SVG format isn't mandatory, but it would help. (To avoid any misunderstandings, please don't just put raster images into an SVG container as embedded raster.) Thanks, and happy editing!
