There is a maximum width if you want them to show up - 800 pix is what I use. This guarantees that your pic wont get hosed.
I use Picasa
Put all the pictures in a folder ready for a batch edit
Click on a picture
Click on edit in picasa
Click on view library
Highlight all the pics
I then add a water mark and rename - then send them to a sub-folder
I just always do it no matter what every time I get a batch of pictures. Keeps things consistent and is really nice if you are putting together a presentation or something where consistency counts
Anyway - it has to be easy or you wont want to do it. Thats what I always tell my wife
Ugh... sounds complex.
I want to think about using oil to transfer heat to the case and then focus on cooling the case
