Alamy vs Getty

Ok, so I'm finding that it is increasingly difficult to sell images online due to a lack of exposure. Getting people to even view your image is next to impossible on sites such as Fine Art America and Etsy without resorting to social media bots, and I kind of disagree with this.

So, I'm wondering about perhaps branching out to stock photography, specifically Alamy or Getty, as I have a MASSIVE back catalogue.

Now, I have uploaded a couple of my poorer images to Alamy to get a feel for the waters, but I'm wondering whether it might be best just to go to Getty.

However, getting information back about Getty is near impossible.

Could someone please outline:

1. How much does a photographer get paid for each image? (I know this varies, but is the top bracket greater, than say, Alamy?)

2. What are the Collections, and how are you assigned to one? Does this mean I am better submitting my best on the first submission? Do different collections pay more/less?

3. Is Getty more selective vs Alamy?

4. Do I retain the right to use my own image to print gift cards/prints, etc?

5. Pseudonames/Aliases as opposed to real name for sign up? ie. can I start with my photography name (Almos Lataan) to begin with, or must I use my real name? (Alamy allows pseudonames)

6. What is the tag competition like vs Alamy?

7. Can I sell Rights Managed on both? I know Alamy allows this, but is Getty exclusive?

8. How do people get on Getty Prestige?

9. Any other image rights concerns?
