1. Keywording: if you want your pictures to be found, you need accurate keywords to be associated with. Instead of thinking about them, there are many sites that can help you. Picniche is one of them. You put a Keyword Phrase in the search box and it will come out with several words. Pay attention to select only some of them, because they may not be pertinent to the context. Stocktagger is another great site and it's more precise than Picniche.
The principle is the same and you have to experiment a little bit to extract good keywords. Here you type a word in the search box and it will come out with pictures of your subject. You select the ones that are most similar to yours and click on “accept chosen images and proceed to the selection of keywords”, sorted according to their supposed relevance. Now select the ones you think are right and it’s magically done.
2. Pictures Cleaning and Improvements: first of all, your photos must not contain any people or trademark object. So with Photoshop or another software like Gimp you have to remove these potential problems. After that it is better to improve your pictures as much as possible, so they can stand out from the mass of millions. Obviuously, it’s up to your creativity and imagination but there are a couple of Photoshop filters that may be useful. You can save some of your files with Noise Ninja from PictureCode (smoothly removes noise) and Topaz Adjust from TopazLabs. The latter must be used with attention because it could generate too much altered pictures. The trick in this case is to apply the filter and then fade it afterwards with the Ctrl-Shift-F keyboard shortcut. Try it and you can really improve your shots.
3. Uploading: the last step is to submit your pictures. Basically you can do it either from your web browser or through ftp (istockphoto doesn’t allow ftp for all and is the only exception among the main sites). The second option is by far the best and allows you to transfer a great quantity of files without having to follow the transfer. You just put the files on a queue and make the computer do the hard work.
At the end you’ll find your files on the destination site, ready for the final refinements. There are a plethora of ftp client softwares, some of them even free. Filezilla is of of the best option for the free branch, it is well known and continuously updated. In the shareware branch, there's a great software called SmartFtp. You can try it for 30 days and then you pay about 50 bucks to keep using it.
4. Finish Submitting: after you upload your file to the variuos microstock sites you have to make the final refinements directly on site. Typically you have to choose the right categories for each image, as well as assign permissions for sale and upload a model/property release. Each site has a separate approach to this last step and if you decided to submit your files to several agencies you could find trouble remembering the whole path. Here's a table where for each site there is a quick reference of the last steps to complete.
