Here is a photo I took last weekend in the Mission District, which I uploaded to Flickr using an Eye-Fi card in my Canon Elph pocket digital camera. I was able to create a link to it and upload it to Blogger, using the iPad for finding the Flickr URL and for the upload.
The upload from the camera to Flickr, of course, had to be done on my laptop.
I also discovered that Blogger will not let me upload photos in my photo library on the iPad. I suppose there is a workaround using email to send the photo to Blogger from the iPad, but I wanted to make it work in the iPad version of Safari, so I used the Flickr link.
