YAPB and Postie

I use YAPB for my photoblog, https://www.dandanellfoto.se and would like to continue with it but… Sometimes I travel light and only use an iPad but that simply does not work with files/images and WordPress.

One solution would be to use Postie with emailing the posts with attached image but I just can’t get it to work with YAPB. I do not wan’t the image in the post so I have set “Use custom image field = Yes” to have the url of the image in custom field “image” but are there any way to use that in YAPB?

Could I change code in YAPB to get it to work with Postie? I see that Postie copies the jpg (and create thumbnails) in /wp-content/uploads/2011/12 but do not know what to do next.

Does anyone else solved this somehow?
