    <p><strong>It can be done, with some limitations</strong>. There are some techniques, and these are exactly how many extensions do screenshots. From your description it seems that you aren't looking for a generic, client side solution to be deployed, but just something that a user or some users could use and submit, so I guess using an extension would be fine.</p> <p><strong>Chrome:</strong></p> <p>I can point you to my opensource Chrome extension, Blipshot, that does exactly that: <a href="https://github.com/folletto/Blipshot" rel="nofollow">https://github.com/folletto/Blipshot</a></p> <p>Just to give some background:</p> <ol> <li>You can do that, as far as I know, only from inside an extension, since it uses an internal function.</li> <li>The function is <code>chrome.tabs.captureVisibleTab</code> and require access to the tabs from the manifest.</li> <li>The function grabs only the visible part of the active tab, so if you need just that it's fine. If you need something more, than, you should have a look at the whole script, since it's quite tricky to get the full page screenshot until Google fixes <a href="http://http://code.google.com/p/chromium/issues/detail?id=45209" rel="nofollow">Bug #45209</a>.</li> </ol> <p><strong>Firefox:</strong></p> <p>In Firefox since 1.5 you can build extensions that use a custom extension of canvas, <code>drawWindow</code>, that is more powerful than the <code>chrome.tabs.captureVisibleTab</code> equivalent of Chrome.

    1. COdrawWindow doesn't work without FF? I thought I saw something about "Chrome privileges" in there... Is that Chrome browser or something specific to FF?

    2. COUnfortunately, I was looking for something that works in a regular website, without the user installing, or even knowing what an extension is. It's also something that needs to happen without their explicit cooperation.

    3. CO@trusktr It's just an unfortunate naming choice by Google: "Chrome" is the part of the app UI (Firefox, Safari or else) that isn't the web page. A plugin that has "Chrome privileges" can access the Firefox UI entirely (since it's XML as well).

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
