Views Image Attach Field stores full path

I still don't understand why, because if I use the default view everything works great ("/"), but when I add a seperate Image Attach field the images starts to show up as "https:=//".

If you think this is a caching problem, do you have a solution for it?

Thanks.

I have normal caching enabled. I cache almost everything.

Here is the scenerio:
I clear my cache while visiting the https://www.domain.com website. I reload so the cache is populated.

Now I visit the http://domain.com website.
What I see in my blocks with image attach:
What I see on my frontpage with the default view:

Also the title and alt attributes are missing with the view.

Great! The img tags dissapeared. Let's try again...

What I see in my blocks with image attach:

<img width="100" height="100" class="image image-thumbnail " title="" alt="" src="https://www.domain.com/files/images/image.jpg"/>

What I see on my frontpage with the default view:

<img width="100" height="100" class="image image-thumbnail " title="title" alt="alt" src="http://domain.com/files/images/image.jpg"/>

I turned off caching and now it works. But I need caching...

Do you have any idea how to fix this? Or what/where could be the problem. I use the Block Cache Alter module (http://drupal.org/project/blockcache_alter) with 'Cache once for everything (global)' settings, which basically enables the views cache mechanism.

But can't the image module just use relative paths rather then inserting the domain to each img tag. This would fix the caching problem.

For example on the title with relative path I see:

<a href="/blog/introduction">Introduction</a>

On the img tags I always see the full path:

<img src="http://www.domain.com/files/images/image.jpg"/>

It's really hard to debug on a production site, but this is what I found:

$node->images[$label] and file_create_url($node->images[$label]) works perfectly. I did see something strange, but only once and I couldn't reproduce it. The problem was, that file_create_url() forgot to put http://domain.com/files/images/image.jpg and I just saw files/images/image.jpg.

So the problem should be with theme() and it's attributes. I checked the $node variable and it was really strange.
When I checked a page with http://www.domain.com it worked perfectly, but with http://domain.com it didn't output anything. So I think the problem should be with this.

Also file_create_url($node->images[$label]) showed always the right URL but on the images the HTML source URL was wrong. So it doesn't always put out what the file_create_url() has created.
