Short of finding the email that it came from, there is no way. If the picture was a sent as attachment and saved, there is no way to determine that unless you still have the original email.

It sounds like either the attachment is corrupted or it's been saved in a format that the recipients computer can't use.
create new folder
By default they are saved to the desktop.
It will have saved it in one of your download or temporary folders. One trick you could use to find it is to e-mail a word document to yourself. Then open that e-mail and the attachment and do a Save As, and see what folder it tries to save it to. That will be where your other file will be.
on the desktop
Anything that can be saved as a file - Be it music, picture or a document. It matters now, aslong as it's in some kind of file format - Mp3, Jpeg, Word document, like I said doesn't matter. Just save what you wish to send, click attachments on an email and find were you saved the item. Then click on it, hit open, and it's attached.
.txt
An email is never saved in your HDD whenever you open it. However, when you download a file that is attached on the email, the file is likely to be saved on your HDD.

I think you mean how to send a saved document. Right click on it and select 'send to', then select email recipients.
