#IMAGE_PREFIX# vs /i – which to choose for static files URL building in Oracle APEX?

You can configure your server files path in Application Builder>Application>Shared Components>Edit Application Definition>User Interface by editing “Image prefix” option.

So it’s better idea to use universal:

<br /><br /><br /><br /><br />
<script type=”text/javascript” src=”#IMAGE_PREFIX#jQuery/js/jquery-1.4.2.min.js”></script>

1	<script type=“text/javascript” src=“#IMAGE_PREFIX#jQuery/js/jquery-1.4.2.min.js”></script>

than hardcoded:

<br /><br /><br /><br /><br />
<script type=”text/javascript” src=”/i/jQuery/js/jquery-1.4.2.min.js”></script>

1	<script type=“text/javascript” src=“/i/jQuery/js/jquery-1.4.2.min.js”></script>

Remember also about difference between three substitution strings for files in Oracle Application Express:

#IMAGE_PREFIX# – points to virtual path of server “images” directory (default /i/);
#APP_IMAGES# – points to static files uploaded with APEX upload utility (so saved in database), that are related to specific application (and only this application can use them);
#WORKSPACE_IMAGES# – points to static files uploaded with APEX upload utility (so saved in database), that are related to the workspace (any application can use them).
