HTML: Image won't display?

Question

I'm kind of new to HTML. I'm trying to display an image on my website but for some reason, it just shows a blue box with a question mark in it. I've looked everywhere on the internet, but none of the solutions seemed to work for me. I've tried:

<img src="iwojimaflag.jpg"/>

<img src="images/iwojimaflag.jpg"/>

<img src="Applications/MAMP/htdocs/Symfony/src/Acme/WebBundle/Resources/public/images/iwojimaflag.jpg"/>

Answer 1

I confess to not having read the whole thread. However when I faced a similar issue I found that checking carefully the case of the file name and correcting that in the HTML reference fixed a similar issue. So local preview on Windows worked but when I published to my server (hosted Linux) I had to make sure "mugshot.jpg" was changed to "mugshot.JPG". Part of the problem is the defaults in Windows hiding full file names behind file type indications.
