how to remove white box around text image

It’s likely something you would need to change in the CSS code — either a border or a margin around the image. Try using Firebug to look at the CSS code for the image and see what you may need to change. Be sure that any changes are made in a Child Theme or in a custom CSS option or plug in.

First of all what is “text image”? But yeah its CSS of your theme.

@wpyogi, thanks.
@d8teen- an image with text.

Hello,

In internet Explorer, there is now a green lined-border around all my images even in previous posts. There is no border in Firefox. All the borders from my template have been removed. Please help.

Try using Firefox with the Firebug add-on for this kind of CSS work.

Sorry, I’m not very technical and am not sure what you mean. Will that remove it from Explorer? Also, I had problems installing firebug.
