When it comes to contributor tools, contests and a sense of community, StockXpert fails epically. To upload files to StockXpert you must first use an FTP program, which is great. You must then dig through the StockXpert website to find where the FTPed files have gone, then port them into the appropriate editor. Then you must either bulk edit a stack of files or visit each file individually to add in categories and keywords. The page where you input this information has input boxes spread all the page and multiple save buttons. Once you get used to it, it isn't that bad but it is really counter-intuitive, making the learning curve quite steep.
Apart from StockXpert's poor uploading method, they also don't do any contests or really any other community building activities. To be fair, this is most likely due to Getty taking such a large interest in iStock and, for the most part, ignoring StockXpert. StockXpert has a lot of downsides but they can be fixed. If Getty put an effort into building the StockXpert community, then it could have another great agency on its hands.
