I often find myself wanting to FTP a photo so I can use it in my blog. I take my photos using a 6MP digital camera and store them in iPhoto.
I don't want the full size photo in a post, but a smaller thumbnail. This involves opening the photo in a graphics program, scaling it down, saving the scaled down version to a temporary location, and then uploading with an FTP client. Afterwards, I need to delete the temporary file. A hassle.
Here's an easier way:
Select the photo in iPhoto and click on the Email button. This will prompt you to select what size you want to mail. Select small or medium (depending what you want). This will open a Compose window in Mail.app with the scaled down photo already in place. You can drag the scaled-down photo directly onto your FTP client and the file will be uploaded. No need to use a graphics app. No need to save intermediate files. A nice time saver! Close the compose window in Mail.app and you're all done!
