I'm pretty new as a contributer here, but I have been using Dreamstime at work for a while now. My attempts to build a portfolio have been modest so far and I mostly do this as a hobby. I have had a few rejections so far, and I can accept the reasons for that. But recently I got a rejection on a submission that had come up in my upload history as "Cannot retrieve file from FTP, please reupload." So I did. Later I discover that I had that second image rejected for being a duplication. Lo and behold I check my portfolio and sure enough there it is!
So I guess I'm not looking to complain about the rejection, only the fact that the cause of the rejection in the first place was initaited by Dreamstime to begin with. In theory too many issues like this could really hurt my approval rating which might impede me if I want to become a more serious contributor down the road.
I'm not too worried about this rejection at the moment, my approval rating is alright for the time being. I guess I'm just curious as to how often this kind of thing occurs?
Well I just got a sale for the image in question, so I can't complain too loudly. I will say that Dreamstime has really been on fire with regard to overall submission time, so I guess that a few glitches are to be expected.
Don't let rejection bother you too much because the kind of work you are into seems to sell very well in Stock Sites and you only going to make alot of money in the years ahead if you keep doing what you do.
The Spreadsheet idea Afagundes posted is a good idea and won't take much time to get started if you don't have alot to catalog to start. I use Microsoft Excel on the computer, makes it easy to know what is uploaded to what site and being a contributor now to eight sites......yesss, I bit off more than I could chew, lol...work,work,work! And I got to start uploading many more in here too.
You try that and I am sure you will will like it and be glad you did later on when you amass huge amounts of files and lose track of what you uploaded and what you did not upload which will be time consuming.
Good Luck & Blessings!
