Another way to convert .MIX images created in Microsoft Picture It! is with Microsoft Word 2002/XP or later.
This can be done by using the insert tool to place your .MIX format image into a document. Once you have done this, go to File > Save as Web Page and choose a location. Browse to this folder. The .MIX image will have been converted to a .JPG file as part of the process. You can now use this image in other applications.
but the default resolution is too low. how do i change it?
