I couldn't get several things to work with Joomla 1.5.8
I did manage to get it going using the new RC version of
Simple Image Pro, but it still errors out when I try to
add the parameters.

I created a work around to clean up display of thumbnails
by putting them in a narrow table, but I still would like
to display ONE image with the :1 option.

These functioned worked for me when I had 1.5.7, so it
may be something with the code change in 1.5.8. Any ideas
on a solution out there?
