DropImageURL is an application that creates snapshots of URLs. In other words it creates an image of the URL's page that includes the portion which may not be visible in your Web browser due to its dimensions being too large. A new option is available for also downloading all images on the URL being imaged, saving them in the output folder.
DropImageURL is part of the Limit Point Software Utilities Bundle: http://www.limit-point.com/Utilities.html. Purchase a Utilities password to activate all the utilities, including DropImageURL. Upgrades are free, new utilities are included.
DropImageURL is also available in the Mac App Store.
