How do I turn screenshots for my computer into acceptable pictures for instructables?
I have an instructable on software to design better curved reflectors for solar cookers (among other things). Anyways, I put in screenshots of how I use the software and of my results tabulated in a html page with the pictures of different reflectors and how good they are in tables. The screenshots are actually fine but when i upload them they turn brutal.
How can i keep the quality of the screenshot after uploading.
This is really important for this particular instructable.
The screenshots show that for a 1 or 2 hour unattended cooktime, there are several curves that are significantly better than a parabolic dish. But they do not show anything much after upload!
I have the most recent one below.
