What is the best way to create a content thumbnail to open a readme file or image?
I know how to create a menu option to open a text file, but I forget how to do the same thing in the form of a content thumbnail.
I haven't tried doing the same thing with an image to see if that's supported or not, but there's a twist, I would like to have the image open with a non-default application. I have Gimp as my default image editor, but it's horribly slow to start so I usually right-click and open with windows photo viewer or something if I don't actually plan to edit the image. Not sure if/how that could be done in this case. the image is basically a tutorial, so I can't just hover over it in the content library to read it as the text would be far too small to see. Of course I can always just retype it as text, but the associated images are helpful.
I have also never experimented with the "other import formats" type of content in the Content Directory Manager, I have no idea what that does, does that come into play here or not?
