I followed all of these guidelines and still nothing.
I`ve tried to get help on the above site,but no one seems to have an answer.
Finally got them to show up in both Basecamp and Mapsource.I had to run them thru Paint again and did a little resizing.Ya gotta down size them for BC and MS.But by golly they are there.Thanks to StuartMW for pointing me in the right direction.
Did 16x16 and 8-bit (256) colour do the trick?
And I enlarged one my 24x24 symbols to 32x32 and it is showing.
