The free portable software Mediaspider has been designed as a bulk image downloader for those three locations on the Internet.

The program window separates the three sites into three tabs, so that users can configure the search and download parameters separately for each of them.

These parameters differ slightly. Only a channel can be selected for 4Chan. The other two sites offer more parameters. This includes a search string, number of returned results, size options and option to skip the first x images. DeviantArt searches seem to require a registered account while the other two do not.

Media Spider displays all images that it downloads in a preview window on the screen. This preview window has the same size as the images that are downloaded, but stays in the background all the time to avoid conflicts with other open windows the user is working with. Be aware that the downloader will download all images of a 4chan forum to the local system.

The program lacks a few options, like an image size limit, proxy settings or a download limit for 4chan. The program downloads hundreds of images from 4chan without interruption, as there are currently no options to limit downloads from the location.

Still, MediaSpider does a good job at downloading images in bulk from Google, Deviantart and 4chan. Great for users who download lots of images from at least one of the supported websites, and hoarders.

The name of the application is confusing. In the software is is MediaSpider, on the developer homepage it is MediaArachnid. The portable Open Source application is compatible with most 32-bit and 64-bit editions of the Windows operating system. (via TechnixUpdate)

A click on a preview thumbnail will open a preview window containing additional information like size, title or format of the selected image. Size buttons on the bottom will load the image in different sizes. These size buttons are automatically adjusted depending on the original size of the image. The same toolbar contains buttons to save the image to the local computer, view it in the original context (which will open the image in the default web browser), set it as the desktop background, copy or share it.

Ginipic is an excellent image search engine that can be used to search for images on multiple image search engines including some of the best places to download wallpapers like Deviant Art or Flickr. The application is a bit heavy on the resource usage but since it does not have to be running all the time in the background it does not matter that much.
