【软件简介】：Photo Watermark 是一款专业的给图片加水印软件，如果你想在网络上保护你的图片，可以试试这个软件。
【软件限制】：15天试用、功能限制。
【作者声明】：初学Crack，只是感兴趣，没有其它目的。失误之处敬请诸位大侠赐教！
【破解工具】：TRW2000娃娃修改版、Ollydbg1.09、Fi2.5、Hex Workshop、UPX1.2、W32Dasm 9.0白金版
—————————————————————————————————
【过 程】：
首先说明的是我手里分析的是V1.2.0.6的版本，天空下载站上的是V3.0.0.0新版，呵呵，小猫上网就不去“喜新厌旧”了。可能有许多地方是不一样的。不过我的目的只是学习CRACK技术。
watermark.exe 用Fi2.5看是UPX壳，但是这个壳再次用其它工具做了保护。如：UPX-Scrambler RC 1.05 ——modifies files packed with UPX so that they cannot be unpacked with the "-d" command build into UPX。
呵呵，看了《看雪论坛精华》里 bottle 朋友的帖子学习了脱壳方法。谢谢 bottle 朋友！为了大家方便我转贴一下我所用到的关键部分。
用Hex Workshop打开watermark.exe：
00000400：5B66 FEFF 0410 4000 0307 426F 6F6C 6561 6E01 0009 2A05 46B3 DFDE FF61 6C73 6504
把00000400处的：5B66 FEFF 0410 改为5550 5821 0C09
保存后再用UPX1.2解压成功。556K->1.53M。Delphi编写。反汇编，根据提示很容易就找到核心了。
用户名：fly
电 邮：fly@263.net
试炼码：13572468
程序根据注册码的不同而分为2个版本，运算流程是相似的，因此我只是记录了第二次运算“Pro”版注册码时的参数。
