Talk:Milk Cattle at the OK Corral

I uploaded the album cover files yesterday. I thought it would be OK because we can use those files freely on the internet and I thought Wikipedia doesn't have any commercial purpose. Thanks to Wikipedia, I gained a lot of information about American musicians like Guns'N Roses, nirvana, and so on including their album cover images. So I believed it wouldn't be a problem. But my files were deleted, so I uploaded them again and those were deleted again. Did I misunderstood about the copyright? (I checked some Korean musician's articles and found out none of them contains album cover images. If it could be a problem in USA, why can't I use it even for Korean Wiki page?) --Suokmoon (talk) 06:42, 18 July 2015 (UTC)
