If you want to put the htm file and the picture file in the same folder, you can first create a folder named img, put the pictures in this folder, then create a folder named web, put the img folder and the htm file in this folder named web, and after opening the htm file with Frontpage, you will find that the pictures inside cannot be displayed. At this point, you can find the picture again and use the picture in the img folder. When debugging on another computer, remember to bring the whole web folder with you.
This is actually a question of relative path and absolute path. Please refer to Baidu for details.
