Tube Helper

I was looking for a tool that could easily scale the image based on YouTube's thumbnail sizes across their site. I quickly found out that sites were charging for this very simple thing that someone with very little know-how with HTML or simply Google could do for free. So I made this quick and easy HTML page that can scale the "myThumbnail.jpg" file across all thumbnail sizes. There is also alternate thumbnails which can be replaced using Notepad++ replace tool using the video IDs.

Feel free to use this tool how you like, it's open source because something like this should not be charged for IMO.

Online Mode Video Thumbnails

It is now possible to change the thumbnails in the src/javascript/<page_name>.js files.

Similar to before you can change the IDs using this part of the code.

  var bNewId = "zv-TS_mEHE4";
  var cNewId = "RNCwBSPTZiM";
  var dNewId = "V2IhvWpcjVg";
  var eNewId = "j8y-_ts_H8s";

aNewId = Thumbnail A "gzKb-JxjyWQ"
bNewId = Thumbnail B "zv-TS_mEHE4"
cNewId = Thumbnial C "RNCwBSPTZiM"
dNewId = Thumbnial D "V2IhvWpcjVg"
eNewId = Thumbnail E "j8y-_ts_H8s"
