I am using google images for my site but i came to know its wrong. If i need any topics like health, autos, tech ... where to find images for those to upload and use in my website... Help me...
For FREE images I have to also throw in my vote for http://sxc.hu , they have one of the largest available open image libraries online! (There are other options, http://www.freedigitalphotos.net/ comes to mind.)
