registering a url for a document is exactly what happens when you call:

<blockquote type="cite" class="clean_bq" style="font-family: Helvetica, Arial; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none;">
<div dir="ltr">html image document: aProduct picture1 data</div>
</blockquote>
</div>
<p><br>
</p>
<p>It’ll create a img similar to <img src=„foo/bar?_s=123&_k=432&5“>. the url comes from calling #document:. it’ll take the data, convert it into a mime-document and register it to get a url.</p>

Greetings,<br>
I have a query about saving instances of a class that are of type image (picture).<br>
For example. I have a Product class. This class must have two photographs of that product. I have to save two instance variables of the Product class, picture1, picture2.<br>
These images must be uploaded from the Product form and displayed after uploading.<br>
In Seaside what would be the best procedure to do it.<br>
I don't know if WAFileLibrary would be the best option.<br>
