Thanks Brian. Yes, I have ACDSee which I use to organize and crop. I rarely retouch - although I may have to start to maintain the standards of this wonderful forum!
If I send a photo to the editor and select 'Resize' it gives me the posibility of changing the pixel count. If I put in '1024' (as you suggest) it automatically sets height at '768' (for a normal 4:3 image). Very often, as I tend to crop most of my photos, the pixel count comes out slightly different. The resulting photo is usually between 250 and 300KB. The photos look OK on the monitor - but do you always lose so many KBs? I read the thread where Amin said we now have 100MB per member and can chose between 10 x 10MB or 500 x 200kb. How on earth do you get a 10MB image to fit on the screen??
By the way, as I posted in Herman's thread 'Filesize of image' in 'Housekeeping', I use a simple little programme called 'Photogadget' which has several preset resizing possibilities (one of which is 1024 x 768), but has the advantage over ACDSee in that it can process multiple images simultaneously.
