Hi,
I am overlooking a recent project handedover from an external contractor.
This project uses, many images which were stored in a as a composite image with a rectangular grid of images in 16x2 array .

The required image is loaded at the run-time using :
Code:
Picture1.PaintPicture PictureClip.GraphicCell(TheIcon), IconLeft, imgTop, IconWidth, IconHeight, 0, 0, IconWidth, IconHeight, vbSrcInvert
I want to add some new Images to this file,but I am not sure how would can I modify these images. Should it be done with MSPaint and use trial &error to pick the IconLeft, IconTop?

Can anybody help me how to create/modify these images at design-time
-Thanks in Advance
