You shold imbed keywords into your jpg files before uploading to the microstock site as a precaution against glitches. Whenever we upload or download files, something can become corrupted or go wrong. It is a pain in the neck for sure.
Please do not burn down the bridge! Here is a website where you can download an excellent program that will enable you to imbed the IPTC code (Keywords and Description) into your jpg foiles before uploading without harming the quality of the image. Go to
www.irfanview.com/ and download the program.
After installing it, open it. In the top toolbar you willse the letter "i" circles in red; click on it and you can then enter a Description and Keywords. Then when you upload to a MS site, your keywords and description appear. This seems to work on all MS sites, but doesn't seem to work on shutterpoint. On that site I just upload one at a time because it isn't a quantity portfolio. I only keep 30 to 35 images at most on their site. When I get a sale it is usually $50 of which I get to keep $42.
If you have to ever upload to other sites, or resubmit to a given site do to corrupted files, the bull work is already done.
