How to remove RasterLayer gray edge

Hello , I add a RasterLayer from JPG file , but there is a gray edge on this RasterLayer picture , how to remove the gray edge ?   Thanks .

screen grab?  perhaps it is just the nodata area if the image is slightly rotated.  You will have to check the symbology for the layer to confirm

It looks like the image was acquired with a border around it, where did it originate from?  Since you are using arcexplorer, there are no image processing capabilities there so you may have to live with it unless you have access to other software which will retain any image georeferencing.  If it isn't a georeferenced image, just bring it into a image package and crop it a bit

This is the RasterLayer.

if you have ArcMap, export the file using a smaller extent so that the border is clipped off...In arcexplorer...well, all it is an explorer and lacks functionality to do what you want

Thanks your anser . This is my picture in photo shop , it has not gray edge , but adding in ArcGIS Explorer , these is gray edge . I do not want this gray edge .

I hope use ArcGIS Explorer only , do not want use ArcMap.

check your photo shop options then...I use this technique in SnagIt occasionally to remove collars ensuring that there is no bounding outline when I save the image

I have had good success with using the option to set a transparency color. (Tools, Appearance, Set Transparent Color, then click on the area you don't want drawn. Whatever color that pixel is won't be drawn for the rest of the image. Nice way to get rid of collars on images.
