Frame around referenced image

In the attached file the image in cell F2, which is referenced via a data validation list in cell E2, has a frame around it, whereas the referenced image(s) in column C do not. Is there either a way to hide/remove this frame or is there possibly another method of accomplishing the data validation reference intent where the referenced image does not have a frame? I went through all of the picture formatting features I could find with no success. Thanks. Office 365.

That solution works if the background/cell color is white, but not when it is other colors. So it worked for the example. But in the picture tab, in addition to Picture Correction, there also is Crop, and crop seems to work for all background/cell colors, so you set me on the right track. Thanks much Bo_Ry!
