I have one question for the portable version of this app:
Does JPEGView need a working directory aka does it need to know what folder it is launched from?
I tried it with and without and it worked but I wanted to ask you to be clear.
Most likely not. JPEGView never uses the GetCurrentDirectory() method. The EXE path is determined from the command line, not over the working directory.
Thanks for the quick reply; thats what I thought and observed.
