    <p>I am trying to upload an image file to piczasso.com from python. My code is as follows:</p> <pre><code>import urllib,urllib2 url='http://piczasso.com/api_handler.php' values = { 'data':open('./imagefile.jpg'), 'tags':'', 'size':'None' } data = urllib.urlencode(values) req = urllib2.Request(url,data) try: response = urllib2.urlopen(req).read() print response except urllib2.URLError, e: print e.code print e.read() print "done" </code></pre> <p>However,im getting "Invalid URL!" as the output. I am however able to upload the image using a php page as follows. </p> <pre><code>&lt;?php /* Simple sample script which uses Piczasso API Documentation about PicZasso API can be found here: http://www.piczasso.com/api.php */ if(isset($_GET["image"])){ /* API sends output in JSON format */ $image = json_decode(rawurldecode($_GET["image"]), true); /* $image array includes information about the image URL and sample links to it: $image["direct"] = Image URL $image["thumb"] = Thumbnail URL $image["image_page"] = Link to image $image["bbcode"] = bbcode for forums $image["html"] = html code Sample table below with image links. */ $image["html"] = str_replace("+", "&amp;nbsp;", htmlentities($image["html"])); echo " &lt;img src=\"{$image["thumb"]}\" alt=\"\" /&gt; &lt;table&gt; &lt;tr&gt;&lt;td&gt;HTML for Websites:&lt;/td&gt;&lt;td&gt;&lt;input type=\"text\" name=\"codes1\" value=\"{$image["html"]}\" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;IMG Code for Forums:&lt;/td&gt;&lt;td&gt;&lt;input type=\"text\" name=\"codes2\" value=\"{$image["bbcode"]}\" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;URL for E-Mail:&lt;/td&gt;&lt;td&gt;&lt;input type=\"text\" name=\"codes3\" value=\"{$image["image_page"]}\" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;Direct Link for Layouts:&lt;/td&gt;&lt;td&gt;&lt;input type=\"text\" name=\"codes4\" value=\"{$image["direct"]}\" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; "; } else { if(isset($_GET["error"])){ /* Possible errors.

    1. COAre the HTTP requests from the python code and the PHP page the same? May be there is some header missing. You might want to check that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
