TBH - I usually just try and find an image (with appropriate rights) somewhat related to the content. Failing that, I'll use an image of some code mentioned in the article.
For me, professional looking header images are a big turn off and often an indication of posts with an ulterior (often financial) motive. I also find there is frequently an inverse correlation (not in every case) between the 'professionalism' of the header image and the quality/depth of the content.

Interesting!
I've never really looked at it that way.
For me it was more a quick win to make the images look a bit neater and all in-line with each other.
I do see what you say, with a lot of publications that seem to put more effort in the headers than the actual articles they aquire.
