There are many image hosting services like photobucket, Imgur, Picasa etc. But searching these sites before downloading is a painful tasks as you need to independently do the search. The Image Collector (TIC) is a freeware application that has been designed to allow the quick viewing, categorisation, and downloading of images from a range of web services.
TIC allows you to choose the web service you would like to download from which includes 4Chan, 9Gag, Deviantart, Imgur, Photobucket, Picasa etc and it fetches the latest available images and displays their thumbnails in a scrollable grid.
You can open the image in full size and also download them. It also has categories, which point to a location on disk, so you can activate a category and download an image, and it’ll be automatically placed into that category’s location.
