[solved] Cannot find image - maybe related to resolution?

Is there a way to save the bmp into my own custom directory with the $ $ wildcard characters?

I tried something like
str bmpFile="$mydir$\like-button.bmp"

but it seems the $ $ only works for special directories?

eg I was hoping this code would allow my macro to search for "like-button.bmp" anywhere as long as the directory is named "mydir"

eg both of these would be fine.
c:\mydir
e:\asdfwerf\mydir

I hope this is clear?
