can not put on picture... help

I made a website which renders the html to a web. If I open the html, I can find the picture. However, if I render the html with urls and views, and then open the website, I cannot find the picture. I tried to use both the absolute and the relative paths, but neither of it can solve the problem. Could anyone please help... I'm having trouble with it for several days. Thanks very much.

can you show me what you mean by "If I open the html, I can find the picture"?

and what is your current html tag to render the picture?
