One Gmail account won't sync but others will?

I think I figured it out I just purchased a lumia 521 as a spare phone and this problem was driving me nuts. I want to thank this thread for pointing me in the correct direction which was contacts...If your like me and a little ocd you put contact pics on every contact even companies....Some of those pics i uploaded to google were png not jpg and those are the contacts that caused me problems. First off to test WP only syncs google contacts in the My Contacts group. So to test remove everything from that group and tell your phone to sync contacts. You will get nothing but the error will be gone. But if you add a contact or move one back and set a jpg as its pic it will sync...move another one and set a png as the pic and the error comes back...If anyone wants to confirm my findings please report back... Hope this helps everyone.

Oh and I used the email client to force a sync when you sync email contacts sync as well

Hopefully the black update comes soon and fixes this. Note my primary phone is a nexus 5
I also really wish google had not dumped EAS it was awesome....

As I said above... black doesn't fix this. I had to export, delete, then re-import all my contacts to get rid of the photos (should have made this clearer, but assumed this was obvious as the thread had already established the photos as the reason why sync doesn't work)

Did you notice the PNG vs jpg issue I mentioned?

I deleted some sent emails and everything syncing again... strange...

I have found it is definitely related to sizes of images on the contacts. An image of more than about 4 or 5kb seems to cause my Nokia Lumia 620 to not be able to sync my contacts.

If anyone is interested I wrote a small Windows program to list all gmail contacts with the relevant image sizes. This enables you to see the contacts that have the largest image sizes, and then you can remove the image associated with the contact.
