Image Pro simplifies the WordPress image upload, resize and management.
Using ImagePro, you can:
<ul>
<li>upload of multiple files directly from your desktop</li>
<li>perform smooth image resize (a perfect resize is created based on your resized picture in the editor)</li>
<li>easily manage the media collection (search, filter by file type)</li>
<li>drag and drop any image to the post and have it resized the way you want</li>
</ul>
<h3>Arbitrary section</h3>
In case of experiencing problems, make sure you adhere to the installation requirements. 
If the problem still persists, take a look at /imagepro/logs/impro.log and see if there are any errors or warnings reported 
If nothing helps, please use the “DBG” link from the “Available Images” panel in the post editor. This will provide debugging information, which you can send back to me for troubleshooting.
Many thanks to phpThumb and KLogger. Also, many thanks to from <webhostinghub.com> for the Spanish translation of the plugin!
Last but not least, great thanks to Jetbrains for their great PhpStorm IDE!

This plugin allows you to Automatically add a watermark to all images as they are uploaded to the WordPress Media Library. 
The plugin uses PNG watermark images with transparency for precise control over the appearance of the watermarks. 
This plugin also supports simple text watermarks with adjustable color, size and transparency. 
The plugin can be configured to apply ‘text and image’, ‘text only’ or ‘image only’ watermarks. 
The user friendly settings page allows for control over the appearance of your watermark. 
The watermark preview feature allows for easy testing of the plugin settings. 
The watermark size is controlled as a percentage of the target image, 50% means the watermark will be half the width of the target image.
