:)You all are giving me a good education here.I m almost ready to sign with one of the agencies. So far Shuterstock seems to be the way to go.

Hello,
I am a newbie as far as uploading my photos to any stock agency. Tried to upload to Shutter Stock last week. I find that task daunting as yet. Got emails back today saying that they needed 7 out of the ten to be accepted, but not what was wrong with them. Oh well another day I guess. Am using a Canon 30D to shoot with so I think my tech things are ok as far as quality equipment. Not sure about sizes pixels wide and long but want to learn that. Any comments would help, thanks.
