StockTagger - Online Keywording Tool

StockTagger is a website that allows searching for keywords (tags) for your images. It works in German and English and is available for online use without fees.

Just enter the main tag you wish to search for and a list of "partner tags" will be presented. You can then select the tags or expand them to get even more tags. After adding them to the list, you can simply copy them and input them in your image(s).

This is an alternative to photokeywords that I have mentioned before. It's less visual in the process, but the results are interesting.

Here's a link for the site's help page if you want to get more information on how it works.
