Is there anyway to use the Imageshack API without PHP?

If I use the ImageShack API just in a form like this:

<form method="post" enctype="multipart/form-data" action="http://www.imageshack.us/upload_api.php">
<p><input type="file" name="fileupload"></p>
<p><input type="text" name="key" value="Your_Developer_Key"></p>
<p><input type="submit" value="Go"></p>
</form>

the browser gets taken to an XML doc, which has the image URL, but 开发者_运维问答is no use because I'm no longer on my site. I've tried loading it in an iFrame and that works, but I can't access it because it's cross-domain.

A Http Post in jquery won't work because I can't send a file in it. I don't know any PHP so using that would take lots of time to learn & setup etc. Do I have any other options?

You mention you know Ruby on Rails.

Posting a file with Ruby is rather simple. See: Ruby: How to post a file via HTTP as multipart/form-data?
