Hi, new to this looking for a couple tips. Any advice appreciated.

I been a member of the site for a while now. I mostly hang in the drop shipping section. But I Made this site a while back for fun it gets 10 views a day and hasnt been updated in a year. I peaked at 100 views. Its picture blog with wordpress.

My First question would it be illegal to use others pictures without permission?
Second if it is how often does it get prosecuted by going into a lawsuit for funds?
Is it way I can get paid off of the pictures hosting wise without getting in trouble? This is where I think the artist or photographer maybe mad
Is it way to go bigger? I just want to make a about 100 a month starting off to get my feet wet. Then I'm going for the gold.
Does word press allow ads or do I need hosting.
I also think I need to change my website name because there is and organization with that name.

I also have another niche I'm going to start soon after reading some of the other post.

Thanks for any advice or criticism.
