Python-Written bulk image watermark Tool

Some time ago want to give SEO over there to do a tool station crawler, using the image recognition (opposing defense is tight ah, asynchronous return to the non-standard JSON structure +referer+ encryption + image four lines of defense.) Hey, the code will not be released.

Just the company to give the whole station picture watermark, just study the image recognition has a useful.

million in advance Google, found a watermark code, modified it to use. ^ ^

PostScript: Also found between 0kb pictures and development code misinformation to the picture path, after the code changed into a picture security detection tool, hey. (In fact, the IO exception, PIL to the exception of the image can not be set directly inherit the IO exception)
