Conducted a quick mobile blogging experiment with Impact Instrument…
We used a cellphone to take photos, and used the same device to log into the blog using the web browser.
From there we composed a quick article and uploaded the images (after we created smaller sizes using an app such as Image Resize).
It helps to take the time to resize photos, because the mobile phone usually takes large photos.
Your mobile blog can survive with images whose width is 1024 pixels wide.
There’s no need to upload images larger than 1024 pixels.
Another bonus is that you uploads will take less time, since you’re working with smaller images.
