display of sketches through browsing.

Dear Mr. Andy Pope,

Thank you for your prompt reply.

Please find attached my excel worksheet for displaying pictures as per the method suggested by you.

In this connection i wish to inform you that the following defects i have observed:
1. There is considerable delay in displaying the picture after choosing from the drop down menu.
2. The quality of the picture displayed is not as good as the source picture which is drawn using excel drawing tools.
3. I have sent to you only a part of my workbook. There are other computations involved apart from display of pictures. After adopting the method as shown in the attached file, the computations part has also slowed down.
Can you suggest how to rectify the above defects.

Thanking you,
regards,
D.S.Rama Rao
