Re: JPEG Rendering on Different Screens
- Hi Michael
You are absolutely right - after bluetoothing back to a pc it is
clear it is not the original jpeg. It does not seem to be solely
network dependent as I have had good and bad results on both ORANGEUK
and TMOBILEUK so it appears their recoding proxy only takes effect
for files of a certain size or resolution. Anyhow thanks for pointing
this out - to be investigated further...
