If you draw something, make vector graphics rather than bitmaps, if possible. If you need screenshots, use png. Never jpeg, jpeg is only for photos.
This is wrong! PNG is as well as JPG or GIF a bitmap graphic. the difference is inly the compression method. Only PDF and SVG are vector graphics. EPS is also a vector graphics format but many EPS images are only wrapped bitmap images. You can check of an image is a vector graphics by zooming into the image. When it becomes pixeled, it is a bitmap.
