This is how I do it using Photoshop Elements 10
#1 File Save as name the file and add Web at the end
(this is going to make it that you save the original big file and this new one
will be the web/sized one)
#2 Go to Image/Resize (a box will come up)
on the square that reads "Pixel Dimentions" go to were it has "Height & Width"
type 600 X 600 another box will come up showing you the file size
you want it around 270 (or play with the ruler to archive smaller size)
select "OK"
#3 Then Go to File - Save As - under format choose JPG
#4 Your JPG will be ready for upload
Hope this helps and if I made a mistake others can help out
