<div>But there's no reason to leave run-time scanning on them, so long as the file-create and file-modify scanning remains (i.e., check each write operation, not each read operation). </div>
<div> </div>
<div>That said, I use PNG, JPG, and SVG exclusively in FrameMaker, and my files open over a network in the usual time: e.g., 400-page manual with 18 chapters; File > Open All Files; about 2-3 minutes. [If that's "slow as molassas" then I'm just used to it after two decades.]</div>
