Thanks all! I think SVG may be more than my simple brain can handle.
What prompted my question is that I was poking around the Sigil forums when I came across the nifty plugin “InsertImageSVG” (plugin to insert and wrap an image with SVG). I then thought, “gee, maybe I should start wrapping all my images in SVG code!”
But while that seems to have benefits for ePub, it looks like it may have disadvantages for ePubs that will be converted to KF8??? (And it definitely has potential for interfering with conversion to KFX, which is not a real concern for me since I’m a KF8 gal, but still worth noting.)
So maybe I shouldn’t go crazy with the SVG plug-in?
(Note also that I’m just talking about wrapping jpg and png in SVG code, not in using SVG images, which is definitely more than my simple brain can handle
)
