Configure Lister - Define view method by file type - look here - http://gral.y0.pl/tc/lister_configure.html - example for DBF extension

From HELP

Define view method by file type
Allows you to choose preferred view methods separately for file types chosen by the user. This is mainly useful when there are multiple view methods for a certain file type, e.g. display icons from program files or display program file structure. Normally this is determined by the order of the lister plugins, but this function provides more options.
If you have defined 2 or more view methods for an extension, pressing '4' multiple times will change only through these methods. If you have specified only one view method, opening Lister with F3 will use this method. Pressing '4' multiple times will change all Lister plugins if they support the file type.

If you use cm_SrcQuickInternalOnly, cm_SeparateQuickInternalOnly, cm_ListInternalOnly or cm_ListInternalMulti, then no setting will change anything, internal viewing will be applied. For cm_SrcQuickView, cm_SeparateQuickView, cm_List, cm_ListOnly and cm_ListMulti everything will work as you set up during installation or in the config file, taking into account the features of the plugin and the listed extensions.

I followed your steps and added the image file to be loaded by Imagine.wlx, but pressing 4 still switches internal loading.
