After upgraded to Opera Mini 3.0, I found out that it can upload photos to blog. I registered an Opera Community account instantly, and took a photo to upload. After uploading the photo, I entered some text for title and content and clicked submit, and the post has been published. It's great!
I was dreamming about an easy way for mobile blogging, and I think Opera Mini 3.0 would be just the right way. It's easy enough to use, and just take a little time to publish a post with one photo. In one day, I can publish 2 or 3 posts without interrupting my jobs or wasting a lot of time.
