Thank you t00fri! It seems I was experiencing whatever iincompatability there was with version 1.04.

Reformat and all, any how when it came time to install the necessary utilities for virtualtex all went smoothly until i ran the script. I got more errors. I had tried everything I could think of before asking for help AGAIN for the same issue. Finally after 2 days of messing with it I was about to request help because i was again stumped, When I thought I would try one more thing:

$ virtualtex test2k.png 256 png
tilesize = 2562048
/usr/local/bin/virtualtex:51: bad math expression: illegal character: ^M

I compared the script I had save in Nano and the script at the above link. They were different. So I went about making the script in Nano look EXACTLY the same as the script from T00fri's site. It turned out only to be 2 or 3 lines that needed to be spaced correctly. Once I was sure it was exactly the same I saved the file, ran the script, and lo and behold it now works beautifully!!
also why are you using Cygwin instead of MinGW witch is much faster
I wish i was though so I could help others with thier questions rather than asking my own.) However When I go to a site that is offering these programs I am quite intimidated because they seem so complex. So I have to come back here and ask those of you who are familiar with them what to do.

from the left Payne in explorer right click on test and select "Open Command Window Here"
Once I was sure it was exactly the same I saved the file, ran the script, and lo and behold it now works beautifully!!
It works great but quite slow(not complaining)

Hi Cartrite,
Thanks for the tip But I think you misread my post

As you can see I have gotten the script to run. Smile It works great but quite slow(not complaining) Wink
from the left Payne in explorer right click on test and select "Open Command Window Here"
type in sh then hit the enter button
then type sh vipsvt.sh *.png 512 png and hit enter
and see what happens
