Ron, I now always resize my photos. Its actually the LEAST time consuming part of posting them here. Once I have all my pics ready to go, I type the resize info once, copy it and and paste it in each one. Probably takes me less than a minute for 36 pictures. And for an even easier method, when I am doing a long post like a photo tour, I usually type it up as a Word document for convenience of spell checking, saving, etc. Once all my pics are loaded into the Word doc it takes about 10 seconds to globally replace "[IMG]" with "[IMG width=800 height=535]". When I'm finished I can copy the entire Word doc into my post.
Sean, as for altering pics, I wish more people would do so. Changes which help me see the course are a plus in my book. So I am all for adjusting brightness and contrast when exposure on the original photo was compromised by sunlight or cropping photos to zoom in on long shots or to remove unwanted items (e.g., carts, shadows of the photographer, glare). This isn't deceitful, but rather helpful. The guys on this site take a great deal of time and effort to carefully present their thoughts in a way that makes sense to others. Why wouldn't we do the same to photos intended as visual aids to those thoughts?
