Just wanted to share with everyone some thing I found today about FB Ad images. Especially those who are confused on what works and what doesn't. This just gives you an idea.

I used this method and it does work. Hope those that are having trouble make use of this.
Don't know how that pic of Britney Spears or ad text got approved, seems like a bad example...
Experts suggest 7 to 10 images per camapign? Im doing it wrong then testing at least 100 haha
Yeah not sure about that either, I'm usually testing 50-100+ depending. Sometime I start with 20+ but still, 7-10 is what I aim for as being 'good' images to profit from. But I've only been doing this a little while so maybe I'm doing it wrong. Judging by my P&L that could certainly be he case 
How does this compare with Shoemoneys post that the boobs have it and the bigger the better?
That article should be targeted towards dentists looking to make there first advertising campaign ever on the internet (you want to test atleast 50 images) + that britney ad is pretty much asking for an account ban lol
Hey, guys, as for testing 50+ images. It should cost pretty much money to test so many images. Say, you start with $0.3 bid. To be sure, whether an image is working or not, you need ~100 clicks, I think. Even if every bid drops to 0.15, whole campaign of 50 ads will cost you $0.15 * 100 * 15 = $750. What's the deal? And it will take time (yeah, I know about automated uploaders, but still).
@bumbarda - Over time, you'll get a set of images that convert well in a vertical. You start with these, but then constantly test some new ones. So, it's not like you're testing 50+ *new* images every time. Unless, of course, you're doing a completely different offer ever time.
Also, and probably more important, you'll find out if your offer converts way before you've optimized your 50 images. If the offer doesn't convert, kill it. If it does, you may be negative ROI, but now you can work on optimizing images. Since you have conversions, it's not like you'd be $750 in the hole.
re: How Long to Run - It's not clicks. It's payout. A general rule is to spend 3x the payout. If nothing converts, kill it. (But, of course, the answer is always more complicated, and depends on all sorts of things.)
