iPhoto and uploading to 3rd party print developer

I have had my iMac up and running for a week now. Previously, I was working with Photoshop Elements on my PC, where I could upload photos to Wal Mart, Black's photography etc to have them print the pictures.

With iPhoto, it appears that I can only access the Kodak 'order prints' option that comes with iPhoto . When I try to upload to any other provider, it doesn't interface properly. The 'upload screen' does come on, but when I 'browse' to add file, I can't seem to get iPhoto to interface and choose my photos.

Am I doing something wrong or missed a trick along the way? I can't really believe that iPhoto only directs you to their print provider, and not one of your own choosing.


Sidenote ** I have downloaded the Aperture trial and if I understand it correctly, one of the features is to allow you to upload to a 3rd party print developer. True?

You could use the export command(Shift++E) to export to a folder in your Documents (For example)and upload to your 3rd party app from that.

Yes, that is the way -- export to somewhere (I use the desktop) and go from there. Users are not meant to muck about in the finder, do everything from the app. Using export will allow you to choose the size (resolution) of your photo.
