I would like to suggest that you change the format you use to save chart images. You use JPEG, which is good for some cases, but being a lossy format, it introduces fuzziness around chart bars. Showing clear bars is probably the major requirement for viewing a chart image, and unfortunately in this respect the NT JPEG images are not "up to snuff."
See the attached pictures. The first is the NT-saved image, called "NTJPEG", and it's 185K in size. The second I captured with my usual method, the Windows 7 "snipping tool," which saves in a PNG format. It is 134K in size.
To aid in showing the distortion created by the lossy JPEG compression, I have included two zoomed-in versions of each image, NTJPEG-ZOOM, and NTPNG-ZOOM, each captured in PNG format. Notice that the JPEG blurs the lines between the bars when zoomed in, whereas the PNG does not. You can obviously see this without zooming in but the zoomed-in version is a quick way to see it. Just looking at the full size images on your screen, you can likely notice the difference immediately.
So the PNG is almost 30% smaller, and is a better quality. To me it's a no-brainer. In addition, many people mark up pictures with other programs after saving them, and as PNGs are lossless, they can be saved and re-saved over and over with no loss in quality, so it's perfect for using as a canvas for additional editing as many chartists do.
For suggestion #2: please add a "Copy to Clipboard" and a "Copy Selection to Clipboard" under Image-> in addition to Email, Save As, and Print. For the "Copy Selection" menu item, the tool could be exactly like the "zoom" tool except that it copies the selection to the clipboard instead of the whole chart. Just like the Windows Snipping tool.
Many traders use skype, twitter, and other interaction tools, and often all I want to do is share a chart (or part of a chart) quickly. Just doing a quick copy and paste into my other application like skype would be quite convenient.
