I think that one of the most important things a blogger can learn is how to optimize photos for Pinterest! If you know how to make your images pinnable, you can greatly increase the amount of traffic your blog receives. Now, I'm not claiming to be an expert on the matter (far from it), but these are the things I think have the biggest bearing on whether people will pin your image or not.
1) Make Your Photos Fantastic
The best thing you can do to make a post pinnable is add a truly brilliant photo. I've seen "amazing" posts go virtually ignored because the accompanying photo was a dud, and "okay" posts getting dozens of pins because I nailed a great picture.
In my opinion, it is not necessary to go out and buy a fancy DSLR camera. You can get good results with a digital camera if you follow some simple guidelines for taking better blog pictures. (Do check out the tutorial I posted last week if you are a newbie who wants to take better photos).
2) Label Your Pictures
An eye catching picture will attract pins from your blog visitors, but you want to attract re-pins and click throughs on Pinterest too. Not everyone gives their pins a proper description, so make a habit of labeling your pictures too. That way, people will know what the corresponding post is about even if the pinned picture is not accompanied by any real information.
3) Watermark Your Pictures
Isn't annoying when you are searching for ideas on Pinterest, and the pin you fall in love with leads to a broken link? Sometimes people accidently mess up the links when they are pinning. Some mean people will also pin your photos but put their own link in, so that your hardwork is attracting click throughs to their website. Either way, a watermark on your pictures will help people track down the proper source of the photo if the wrong link is attached to it.
4) Portrait Performs Better Than Landscape
Vertical and square pictures are far more likely to be pinned than horizontal ones. Seriously, take a look at your feed on Pinterest. They will also display better when someone performs a search on Pinterest, as the search results are set to a certain width (rather than height). Therefore, portrait orientated photos display at a slightly larger size and are more likely to grab people's attention.
5) Add ALT And Title Text To Every Photo
Add a title and ALT text to every blog picture. Not only is this good for search engine optimization, it will be the text that pops up when someone pins your photo. It means that more pins from your website will end up with a useful description. To add the text on Blogger, click on the photo in Compose mode and select "Properties". It will bring up a box for adding 'Title Text' and 'ALT text'.
