img src=" not working??

It might help if you actually posted a sample of the code that you have been using.

please enable DEBUG to see if you get any error mesages; http://codex.wordpress.org/Debugging_in_WordPress

the output of your site seems to end suddenly …

where exactly are you adding the posted code section?

I can see this in the html of your linked site:

<div class="main">
	<div id="link1">
	<img src="http://www.extensionsbymarina.se/wp-content/themes/room/images/link1.jpg" alt="" />

which indicates that your code is executed properly; the image is simply not where the url points to;
where do you have the image stored?

please double check the location of the image.

there is definitively no image at http://www.extensionsbymarina.se/wp-content/themes/room/images/link1.jpg

this is how your site’s html ends:

<p>Bäckvägen 118</p><p>
129 33 Hägersten</p>

</div>
</

so something is broken in your theme.

btw:

here it works

not really – the same problem at the end of the html output. although, the images seem to show.
