Clifford, i too spent some time looking at this and here’s my take. it seems that since we have the compiled version of the launcher all the files are already embedded. what your seeing in the source is basically pointers to the files that used when he compiled the source. however they do not exist in the folder it points to(hence the yellow !). so essentially in order to recompile it you will need to add .png for each and every file prior to compiling. or at least that is how i interpret it. let me know if you sort this out as i would like to do the same and create a new launcher page.
