I am GLAD you are watching me! and answering

When you say 10x15, what does that mean?
I use Microsoft photo editor, to crop, etc. before I upload. I do go in and change the pixel size from 300 to 96. I don't know what dpi.
Here's another ? - Auctiva says that they auto resize our pics before putting in an auction - should I be doing that before I upload? My pics come off the camera at 900x1200. I don't change that before I upload.
How would you like to take a look at one of my auctions and see how long it takes it to load for you? Pretty please?
