Confession:
It all depends on the nature of the websites.
The first two are great for consultancy advertizing. Thefirst for serious , get down to business type ads. The second if you are more into HR and personal improvement type consulting.
#3 and 4 I would leave off completely. 3 has some possibilities if advertizing computer related skills but people looking for computer skills would not be impressed byu the smiling faces in these pics
For pics 5 & 6. If you are a guru of some kind these could be useful. Too casual for business and too 'out there' for anything other than well.. something out there.
So the pics may be great depending on what image you may want to project.
My opinion and two cents... and Hey, 2 cents Canadian is worth far more than it was 6 months ago!
