 * I love this plugin, but I can’t get the thumbnails to showup on my site. I did
   add the following code to the custom CSS section, but it’s still not coming up.
   Do I have to change some of the coding in this code?
 * > <?php
   >  add_action( ‘iworks_upprev_image’ , ‘default_image’ ); function default_image(){
   > return ‘<img src=”image.png” alt=”” />’; }

 * Hi Marcin,
 * I changed the code to the code below, but it still isn’t working.
 * > <?php
   >  add_action( ‘iworks_upprev_image’ , ‘default_image’ ); function default_image(){
   > return ‘<img src=”proper image uri” alt=”” />’; }
 * Am I doing something wrong?

 * If I use a specific .png or .jpg file, doesn’t this mean that the same logo will
   apply to all the thumbnails?

 * Yes. If You want to have other, for example depend on category, You must write
   some code to handle this.

 * I am having the exact same issue, though before updating upprev to the most recent
   version, I never had any problems with the images. I want the associated image
   for each post to be displayed in size 75 x 75 pixels.
 * There used to be an option on the plugin which would allow you to set this dimension,
   but now I see that since the option has disappeared, my images won’t display 
   either. It seems like there’s a new bug with this version. Can you please provide
   a fix? Thanks for your help!

 * Thanks so much for this…I reinstalled the plugin and now that option is appearing
   once again. I guess my install the first time went wonky. Thanks for the help!

 * Well, perhaps I spoke too soon. Now for some reason, this option is missing again.
   I took a screenshot to show you, but I don’t guess it’s possible to upload it
   here.
 * Just know that the image option is no longer available again.

 * Now all of a sudden the option is suddenly there again…very strange and it had
   nothing to do with using a different browser, clearing my cache, etc. I’m not
   sure why this keeps disappearing randomly.
