i think that you already offer news data about the cars on other areas of the site... remember that all cars have things like tires, oil, fuel, etc., in common, which is good text fodder... think about it from the standpoint of the advertiser.
Very cool site. Great work is always appreciated. I loved the site. But Donate ? I wouldn't do it. Why should anybody donate ? If you want, sell the images, but what kind of thing is it do donate ? Just give you the money because you are nice ? Do you think its fair to ask for donation ? I'm usual that donations are give to higer reasons than car web site.
The problem with a photo gallery script is that google crawling robots will think that we use any cloaking pages or something like that.. Because the only thing that changes in every pages is the current image`s name & and other things are the same as the other pages.. therefore google doesn`t crawl all the pages. If google doesn`t crawl all the pages it is difficult to get relevant ads from google adsense.
i use javascript for photo galleries, and i've never had a problem with google penalizing my pages, or failing to find the content. for the scripts i use, the full url to all the photos is typically hard-coded on the web page... it's not hidden inside of a script.
Sorry, only just saw this. You'd be surprised. Twice I have received a $50US donation from my visitors. Both times I was more than pleasantly surprised! Thanks for the comments on the site. Saragan: Thats not entirely correct. My gallery with over 12,000 user uploaded images manages to pull in a PR3. And its just a gallery with pictures.
