Problem with attaching/uploading images after editing in Aperture

Question

After I edit images in Aperture, I frequently have trouble uploading them to Flickr or attaching them to an email message because the attachment/uploading tool cannot find the image. When I go to Aperture to view images, the edited image is there; however, it does not appear among the images in the folder where it is stored when I attempt to attach it to an email message or upload it to Flickr. I've tried searching for it by image number and that doesn't help. This never happens to unedited images, only to the ones that have been edited. The issue tends to go away after some time - for example, when I try to repeat the action the following day, the image is "back" where it should be. However, simply restarting Aperture, Flickr, or my browser doesn't help. Obviously, this is extremely frustrating, as I edit virtually all my photos before sharing them. Has anyone experienced this issue and have you been able to figure out a solution? Thank you! Oh, one last note: I've never experienced this issue when editing images with other software, such as Photoshop or Picasa - it only comes up with Aperture.

Welcome to the user-to-user forum.
Aperture creates the adjusted images as needed, on-the-fly, from the adjustment instructions saved in the Version file. Aperture also keeps Previews of these images, both for its own use, and to share with other applications when a lower-resolution JPG is sufficient. That is why you cannot find your images using Finder or other "File→Open" attempts (which is what you seem to have been trying).
(Previews are worth learning about. Consult the User Manual (a/k/a the Help file).)
In order to create a file, you must export your adjusted Version using Aperture.
Any application which has access to the OS X Media Browser (Mail does) can access these Previews.
There is a free utility which gives similar access to all applications: iMedia Browser. It looks good, but I haven't used it enough to comment.
You should also be able to access images of your adjusted Versions via the "Media" category which shows at the bottom of the sidebar of applicable OS X "File→Open" dialogs.
But the easiest way to email a image from Aperture is simply to use the toolbar icon or the keyboard shortcut "{Option}+e". Select an email program and an image exporting preset (which sets the size and other parameters) via "Aperture→Preferences→Export".
Others may have advice for Flickr. I don't use it.
