Custom button images cropped in Java version of Image Uploader

I have created custom icons for the Select All, Deselect All and Send buttons. I add these with the following code :

iu.addParam("ButtonSendImageFormat", "Width=192;Height=40;UrlNormal=./images/upload.gif;UrlPressed=./images/upload.gif;UrlDisabled=./images/upload.gif");
iu.addParam("ButtonSelectAllImageFormat", "Width=98;Height=40;UrlNormal=./images/selectall.gif;UrlPressed=./images/selectall.gif;UrlDisabled=./images/selectall.gif");
iu.addParam("ButtonDeselectAllImageFormat", "Width=97;Height=40;UrlNormal=./images/deselectall.gif;UrlPressed=./images/deselectall.gif;UrlDisabled=./images/deselectall.gif");

In the ActiveX Image Uploader control it looks perfect but in the Java control, although the button area is high enough to cater for the buttons, there is some padding above and below the buttons and the icons are clipped at the bottom.

Screenshot 1: Using standard buttons:

[Image was removed]

Screenshot 2 : ActiveX custom icons:

[Image was removed]

Screenshot 3 : Problematic Java custom icons:

[Image was removed]

Can anyone help me fix the Java version?
