I'm getting a bit of deja vu here... this type of discussion has been up before.
At the end of the day it comes down to: how does google treat the src=
As far as I know (and the tests that I have heard of) Google will not look at the src= URL and use it for ranking or discovery. However, I could be wrong there.
