It was difficult to make out the words garyimages.com and motorsport photography. The logo was a bit large and dominating the name. Even in
#64 where the words are front and center - it was difficult to make out the name of the company/website. I can see where you were going with the red stripe - making it a G at the end. But again the words are a bit small.
Is the white stripe supposed to be the " i " in images? If so it was difficult to make out the rest of the logo with the stripe and the red upside down " L " to represent the " G " in Gary.
Out of the 4 - the best is
#64
