This plugin lets you place a faded border around any image file.
You have to apply the CSS class "gradient" to the image. To do this, insert the image into your post or page. After inserting it, click on it, and click the icon that appears in the corner. A window will open allowing you to edit information about the image. Click the "Advanced Settings" tab, and add the word "gradient" to the CSS Class field. Click "Update", and then publish your postpage. That's it!
Yes. In your WordPress Admin Panel, go to Settings, and click the Faded Borders on Images link on the Settings sub-menu. Using the admin screen that appears, enter the color you would like to use when fading the edges of your images, and click "Save".
Using CSS or the raw code of your theme, apply the class "gradient" to your images. Be sure you have permission before you edit your WordPress theme, if your theme is not publicly licensed.
