Times has changed. No longer are blogs restricted to just text. Photos have become ubiquitous in all blogs.
Should you bring along a digital camera? Or camera phone? Unless you are photography buff, a 2-3 megapixel camera phone will do just fine for prints and also for blogging. That way you only need to carry 1 charger on the camino. The only requirement is that your phone must have support for external memory card for storage.
The external memory card that is bundled with the phone are usually small (around 256-512 Meg). Quadruple the capacity by investing around 30 USD for a 2 Gigabyte card. On my 2 megapixel camera phone, the estimate is around 4800 photos! That's more than enough for a few caminos without having to remove any photos from the card.
There are different types of memory cards for the camera phone. The newer the phone, the smaller the card tends to be. They are basically SD (small), MINI-SD (smaller) or MICRO-SD like in the photo above (tiny). Make sure you have a USB reader for the card. If you buy an additional MICRO-SD card, they usually throw in the reader for free. If not, a USB reader usually cost only a couple of dollars.
With the USB reader, you can plug it into any computer during your camino and have access to the photos stored in the card. This is also necessary if you want to post images to your blog. And at the end of your camino, you can use the reader to move your photos from your camera phone to your computer.
