You've hard-coded a relative link to your logo image - see screenshot. It will find it at the top level and the first level down, but not below that.
Please Google "relative URL's." The URL is relative to the location of the current page. If the logo file is two or three levels up from the current page, that relative URL won't be able to find it.
You could probably fix this by using the
absolute URL for the logo image:
<p style="text-align: center;">
<a href="https://al-j.net">
<img src="https://al-j.net/res/CAlogo.jpg" width="155">
</a></p>
That wouldn't work before the album was uploaded, but would be OK after that.
