how do you?

How do you resize images in DPP to upload pics here?

I have cs2 and use it 95% of the time im just curious how to do it in Canons software DPP?

Select 'Convert and save'. In the window that opens select jpg as the file format with a compression of around 6 or 7 and then check the Resize box at the bottom. The current pixel dimensions will appear, change them to what you want (around 500x750 is good).
Don't worry about 'Output Resolution', it doesn't matter. If you uncheck the 'Embed Profile' box your file will be a bit smaller and upload faster. If your image was not already in sRGB space, before you begin this operation be sure that in the main window in the menu Adjust/Work color space, sRGB is selected.
