Current primary setup is latest MikTeX, using WinEdt 9.1 as the front end (recently did a minor upgrade from WinEdt 8.xx -> 9.1. I know its not the most recent, but...).
At any rate, very simple problem. If I have a file (MWE below) that has no graphic, then MWE complies fine using either PDFLatex or PDFTexify (ctrl-alt-P). But, the moment I add a graphic (either .jpg or .png, makes no difference), the PDFLatex still works, but...PDFTexify now halts with a critical error that size/bound box of the image can't be determined.
Since this MWE compiled just fine at one point, it occurs to me that the options being passed to the MikTeX executables are no longer correct. Or, the executable WinEdt should be looking for has changed. Or...both.
For PDFLatex (which works), using pdflatex.exe as the executable, with --enable-write18 -synctex=1 %0 as the switches, and "%N%T" as parameters.
For PDFTexify, I have tried texify.exe using --pdf --tex-option=-enable-write18 as switches, and "%F" as the parameter (this used to work fine). Changing to pdflatex.exe as the executable doesn't work either.
Suggestions? Pointers to the obvious? I'm 99% sure the problem is some funky interaction with latest MikTeX executables, which executables WinEdt 9.1 is pointing at, and perhaps the switches and parameters set in WinEdt, but can't figure it out.
Here is a completely trivial MWE which probably isn't remotely necessary, but...
