BatchPurifier LITE will remove metadata from JPEG files in batch.

Image Renaming will let you rename your photos with a name based on date and time.

Migratr will allow you to move your photos between some popular photo sharing services (e.g. from Flickr to Faces), and it will also migrate your metadata, including titles, tags, descriptions and album organization.

Viewer2 will let you organize your photos based on their physical location on the screen, just as when you pile photos on a workdesk in real life. It supports tags (fully searchable). Its database allows you to track and search your images with queries similar with those you use to search the web. You are not restricted to a normal list-style view of the images, but you can see the full folder or all the search results at once. You can treat the images as you would handle photos in the real world: move images of similar subjects into one pile for quick tagging and move interesting images in their own pile for later examination. The program starts in full screen view, which can be very annoying.

VisiPics will help you find duplicate pictures. Detected duplicates are shown side by side with pertinent information such as file name, type and size being displayed. An auto-select mode lets you choose if you want to keep the higher resolution picture, space-saving filetype, smaller filesize. Of course you can also manually select the images you don’t want to keep.

digiKam will let you organize your photos in albums which can be sorted chronologically, by folder layout or by custom collections. You tag your images (which can be spread out across multiple folders), and digiKam provides ways to browse these tagged images. You can also add comments to your images. A tool assists artists and photographers with reviewing their work ensuring the highest quality.
