こんにちは。かみちゃん です。
> 別面でjpeg保存する部分まで、vbaではできないのでしょうか？
ｈｔｔｐ://www.vbalab.net/vbaqa/c-board.cgi?cmd=ntr;tree=57318;id=excel
で、kanabunさんが紹介されていた
>> シート上の図や画像をjpgファイルとして保存するには
>>
>> SaveCBPictureAs
>>
>> というshiraさんという方の関数
を利用すると、以下のような感じてできませんか？
なお、
ｈｔｔｐ://www.vbalab.net/vbaqa/c-board.cgi?cmd=one;no=69743;id=excel
の質問と何が違うのかよくわかりませんが、
以下のコードは、アクティブシートのすべての
msoPicture をファイルに保存する方法です。
すべてのシートの特定のセルにある msoPicture であれば、これをベースに修正すればできると思います。
