This question has come up in several different places, so I thought I would clarify things here. It is not possible to us the iPad's web browser to upload pictures to YLF. This is not because of any bug in YLF, but rather, a limitation of Safari (the web browser) on the iPad. It does not support file uploads.
In order to enable easy photo uploading from the iPad, we really have to build a YLF iPad app that has this functionality. We will get to this at some point, but in the meantime I'm looking for a workaround. If I find one you will be the first to know.
