This script converts image formats using only window's gdiplus.dll,
among bmp, jpg, png, gif, tif. I think Bruce will implement this
feature eventually into PP, then, stil32jp.dll wouldn't be needed
anymore. Until then, may use the script instead. It uses only default
settings for conversions. The usage is:
.ImageConv(sNameFr, sNameTo)
e.g., .ImageConv(?"...\test.jpg",?"...\test.png")
------------------ ImageConv.PowerPro --------------------------------
@Convert
args sNameFr,sNameTo,xNameFr,xNameTo
local sTypes,nCodecs,nSize,pImage,pToken,si,ci
dll.call("MultiByteToWideChar|ui ui s i s520 i",;;+
0,0,"sNameFr",-1,"xNameFr",260)
dll.call("MultiByteToWideChar|ui ui s i s520 i",;;+

0,0,ci[19*i+12],-1,"sTypes",272,0,0)
if(index(sTypes,file.type(sNameTo)))
break

for(local j=4;j;j--)
