This project is not covered by Drupal’s security advisory policy.

Websnapr Field provides a simple means to show thumbnail images (not popup previews but actual IMG tags) for external web pages. It extends the Link module with new formatters which translate a URL into a linked IMG tag with a SRC attribute encoded for use with the Websnapr service.

See Websnapr's site for details of their automatic on-demand thumbnail service.

It’s a work in progress rather than a finished item: it currently only provides the two small sizes of image which are generated by Websnapr’s free service, and its HTML output is perhaps a little limited, though theming overrides could be used to improve it in that respect. For now, it’s Drupal 6 only, though a backport to Drupal 5 would not be hard.

Update: Now confirmed as working fine with Views.

The module is very small: all the real work of validating and managing URLs is done by the Link module, while Websnapr Field simply provides a set of formatters (currently just two, one for each of the two image sizes) by which URLs can be displayed. You first create a URL field and choose the Link field type, then configure it to use Websnapr for display. For screenshots to work, you also have to enter your Websnapr key (as provided by Websnapr after registration) in a separate administration panel.
