image_process relative URL issue?
I am using the latest version of image_process plugin with pelican 4.5.3, using Python 3.8.5 on OSX Catalina using bootstrap2 theme. After following the documentation I only get proper results when served locally not remotely. i.e. while:

would lead to correct URL / displayed image, both when served locally and on the remote server, the following line:
<img class="image-process-large-photo" src="/photos/test.png"/>
leads to a tag with relative URL
<img class="image-process-large-photo" sizes="(min-width: 1200px) 800px, (min-width: 992px) 650px, (min-width: 768px) 718px, 100vw" src="/photos/derivatives/large-photo/800w/test.png" srcset="/photos/derivatives/large-photo/600w/test.png 600w, /photos/derivatives/large-photo/800w/test.png 800w, /photos/derivatives/large-photo/1600w/test.png 1600w"/></p>
which is only locally visible, but on the remote server does not find it.
Is there a way to change this behavior?
thanks!
Remotely, are you serving your blog directly from the website root? The URL to the photo is assuming that is the case.
You may need to look at setting SITEURL in your publishconf.py to adjust for this.
