Use of fonts in blogs
My questions:
I make quote-pictures to one blog. I'm wondering, the pics are not for sale, can I use "100% free" fonts to make these pics? Blog itself has some ads time to time, but these fonts are not to any ads of course. They are only used as a visual material to the blog. The blog doesn't make any money with these pics.
Should I ask from the makers of the font.
If the font is 100% free, it's courteous to inform the author of how you've used their work, but you don't need to ask for permission, in advance. You would need to ask in advance, if it's a
Free for Personal Use font.
Do you, directly or indirectly, receive any income from the ads on the page, or are they just there as part of a free hosting domain, like "geocities", from years ago?
