It sounds like you once had ACDSEE on your computer; this is, as I remember, a graphics editor application. You will need to change your FILE ASSOCIATION, if you have perhaps deleted the ACDSEE application..
Go to the file in question. Let's say it is a JPEG.
Right click on the file.
from the drop down menu. In the General
tab, you will see the file type, and the application used to open it. Here, you can change the application by clicking on, oddly enough for Windows, Change
. (I'm using XP for the example, but all versions are similar).
Another menu will open to show you the available applications. I recommend using Windows Picture and Fax Viewer, but you may have a favourite graphics editor listed and want to use it.
At the bottom, make sure there there is a check in the box next to "always use the selected program to open this kind of file." Thereafter, all JPEG files will open with whatever you have selected.
You may, to move to the second question, have to physically go to Yahoo's E-mail page, compose your message there, and then attach the file to your message. If you are using a POP E-mail application, you must set up a separate account for Yahoo or Google.
I hope this helps.
