File Copy, Then Execute .exe

I have two userform one if useing the getopenfilename to popluate a listbox. and then i use these listbox item withen this code to copy the files into a new folder. This works ok.

Then i copy a program into the same folder jpegresize.exe this program makes resized images of all files in its directory. by defult this program should only deal with these files. though what is happening is instead of using the files in the new folder it running on the files where the originals where copied from. (hope that makes sence). Though if i run jpegresize.exe from the new folder or command prompt it. It runs like it should. So i cant figure it out is there somethink the the shell and wait is passing that it shouldnt be.
