Not sure what you are asking exactly but if you insert <<smallimage>> into the html it will replace that with the relevant poster image albeit that image is the reduce size version used in the wall feature.
If you want to use the full size picture, it has an extension of tbn. Now I have opened those tbns in both IE & Chrome & they do display correctly....so it may not be an issue.
If you wish to access the full sized image you probably will need to do some search & replace on the created html file.....
So you would put a link in your html to the <<fullpathandfilename>> which will put into the html file the full path to the movie i.e. c:\movies\2012.avi
You will then need to search & replace that with c:\movies\2012.tbn
so in this case you would search for '.avi' & replace with '.tbn'. You can use notepad to open the html file & perform the search & replace. I suggest the dot avi to avoid changing any unwanted occurances of just 'avi'.
If you have other movie formats such as divx or mkv etc you will need to repeat the process to search & replace those as well.
Unfortunately whilst this method will work it doesn't make it easy to repeat when you add new movies....
Perhaps you can suggest to Billy that an new token could be added to point directly to the fullsize poster tbn.
