Hello again Allia,
Thank you for taking the time to answer me.
What I am trying to achieve is to modify what seems to be core files in the ow_system_plugins folder such as the sign in page for example.
I need to display some images there, and the only solution I found so far is by using an empty div with an image background. I then put the reference to the image in the css file.
What I would like to do is the following :
<img src="{path_to_the_image_folder_of_the_theme}">
I saw that some tags are existing but couldn't find a list of all the tags available in the documentation.
Also could you please advise me on how to override core files a good way? I am used to create child folders or themes in WordPress and Magento for example and would love to know if that is possible in Oxwall.
I noticed a "base" folder in "ow_system_plugins", does it mean I can create a "custom" folder for my changes? The main goal of this would be not to loose any changes I made when upgrading to newer versions of Oxwall.
