Same skin as above, but we've manually removed the "thumbnail" in order to minimize the size. The "thumbnail is the last item in the skin as ,"thumbnail":"A_VERY_LONG_BUNCH_OF_LETTERS"}. So to remove the thumbnail, delete the comma just before the quoted word "thumbnail" until just before the closing curly bracket. The closing curly bracket must not be deleted because this is the character that closes the skin code.

"..yada yada...":1}],"thumbnail":"ABCD..XYZ"}

would be:
"..yada yada...":1}]}

... notice curly square curly? Since we did not delete the last curly bracket.
