Yes — headings detected in the TXT are mapped to the EPUB navigation document, so e-readers show a working chapter list and let readers jump between sections.
我的 TXT 中的图像是否在 EPUB 电子书中生存?

Yes — embedded images in the TXT are carried into the EPUB and scale to the reader's screen. Very large images are resized to sensible ebook dimensions so the EPUB file stays light.
Ebooks favor reader-controlled typography, so most readers override embedded fonts. Structural styling (bold, italic, headings, lists) is preserved; decorative page design from the TXT is intentionally simplified for reflow.
