The unregistered version is fully functional in its button design capabilities but is limited by a watermark seal found on each button design.
Purchasing Likno Web Button Maker entitles you to:
• Export and add your buttons to your web pages without the intrusive watermark found in the trial version.
• Priority based customer support.
Apart from the features above you also get benefits such as:
Reliability: Accumulated expertise in our graphics development.
Upgrades: All minor updates of the program are for free.
Support: Quick and thorough answers from our dedicated support team plus detailed documentation.
Not to mention that you would be contributing to Likno Web Button Maker's growth as the registration fee is invested in its rapid development. More powerful features will be available to you.
