Vector images are nice and clean. I have Embird and 5D Pro, both work well with jpg. And I often use photos I took, which are jpg as well.
That's good, I'd like to try from my photos. I 've taken a lot of flower pictures through the years. Be nice to do them.
If WMF/vector graphics are available, I prefer to use them...they are much "cleaner" to use...however all will work with my softwares...I have Janome MBX ver 4.5 and also Palette 9.
