There is something stressing me a lot.

I have a forum, and people posted some photos sometimes, to illustrate their claims, or things like that. But I don't know if some of these photos are copyrighted or not. I have a message stating that if you post a photo, you need to ensure you are doing it in a legal and fair way, but I don't know if people are really minding instructions! So, last year, I decided to pre-moderate all messages, and disallow photos. But I can't go through all the posts made before and it worries me a lot. I have a a button to report issues, and also, I made so that images be re-sampled to 150 x 150 pixels. I thought it 's small enough to be informative only.

What's your thoughts ?

Also, I am in Spain, what if an American (individual or company) wants to sue me ? How can I find a lawyer to represent me overseas ?

Ps: of course if one day, someone asks me to take down images, I'll do it immediately, without trying to challenge this.

@Peter_S
There is something called fair use and what you describe will likely fall under that.

That said, your problem is not being sued, specially since you are in Spain. It is unlikely that anyone will go through the expense of trying to sue you overseas. How much could they possibly claim before you go bankrupt? The bigger risk in my view is if your are using AdSense. Posting copyrighted content without permission is against AS policies and that can get you banned.

Further to that point as it relates to this topic, for the reason described above, any changes to the copyright laws could have big implications for Adsense publishers that have had content that was previously acceptable. This could cause publishers that have older content to review, delete or modify countless pages. This could amount to a significant cost for some.

Thank you NickMNS, it's making me feel relived. I know I am silly, but everything worries me easily :). As for adsense no problem, I also prevent it from showing on page with photos posted, just to be sure.
