将第一帧从 GIF 导出为 PNG

我想你也许可以帮助我:-)
所以我刚刚启动了我的网站，我将在其中上传一些 GIF 并将它们显示在首页上。
截至目前，我使用脚本来显示 .png 文件，当鼠标悬停时，会显示 .gif 文件，您可以单击它，这会将您链接到 .gif 文件。

所以现在我每个 GIF 都有两个文件； xxx.gif 和 xxx_thumb.png ——但是，我希望它能够自动化并考虑一个简单的脚本。
用伪代码表示：

get .gif
  rename to 1.gif
    if 1.gif taken? rename to 2.gif
  get first frame
    export first frame as 1_thumb.png
      if 1_thumb.png taken? rename to 2_thumb.png
load new picture? (y/n)
  if n
    exit
  if y
    start from step 1

这样的东西太棒了——编码有多难？ Ruby 或 Python 可以完成这项工作吗？
这可以通过网络应用程序实现吗？然后将 .gif + .png 作为电子邮件发送给我？ <-- 还没有必要:-)

感谢您阅读本文！

I thought you maybe could help me out here :-)
So I just launched my website, where I will upload some GIFs and have them displayed on the front page.
As of right now, I use a script to show a .png file, when a mouse is hovered, the .gif shows and you can click on it, which will link you to the .gif file.

So right now I got two files for every GIF; xxx.gif and xxx_thumb.png -- however, I would like this to get automatized and thought of a simple script.
In pseudo code:

get .gif
  rename to 1.gif
    if 1.gif taken? rename to 2.gif
  get first frame
    export first frame as 1_thumb.png
      if 1_thumb.png taken? rename to 2_thumb.png
load new picture? (y/n)
  if n
    exit
  if y
    start from step 1

Something like this would be awesome -- how hard would it be to code? Would Ruby or Python do the job?
Would this be possible with a web app, then send the .gif + .png as an email to me? <-- not necessary yet :-)

Thanks for reading this!
