I think image ads is the best choice for photoblog because - there are more visually appealing for your readers than text ads - it is the best choice to 'compete' with your photos (put at the top of your blog) - it's larger and easy to see - much more attractions and beautiful My favourite image ads are Medium Rectangle (300 x 250). Try to put the image ads side by side and your ads will attract more attention!!
good advice for a photoblog. Also you can add a 728x90 (text & images) just below your (300x250 & photo)
Yeah I think it so.Image add is the best choice because its attract people more to pay attention.I'm also going to add image in my blog to gather more traffic.
Another thing to consider is that sometimes you might accidentally break the Adsense TOS by having text ads beside an image in a way that makes the image look like a navigation icon, when using text ads.
Yes I agree. But i feel there is no harm in trying to use other forms of advertisements also on some other pages.
