Apologies, recently bought an A700 (my first DSLR) and have been out happily snapping away - but would now like some critique on some of the pictures I've taken to learn where I can improve for the future (yes I really am that new and green to all this so very keen to learn). And recently new to Dynax as well - what a great knowledge base!
Have been reading about uploading pictures - I've got the bit about 200k max and 800 pixels but how on earth do I get my pictures that size in one hit - I'm lost as each thread I've looked at seems to have links to other threads, which is fine, but sometimes I'm finding I'm going full circle and back to square 1, just come from a different route! Or the conversation goes off into using Elements? or Photoshop (which I don't have). I can't seem to find the definitive "this is how you re-size your photo's thread" (maybe I'm just being dim).
Is there a simple way I can re-size my photos please (I've been shooting in JPEG) that some kind soul can point me at using Paint, as that is all that I have available to me to do this! I know how to resize images using paint to get under 200k max, but how on earth can I tell if they are 800 pixels max?

All help appreciated, thank you in advance. Operating system in Win7.
