Resize images within the datagridview

Your question is not well explained. How are you displaying your images in your DataGridView? What column type are you using? If you are using DataGridViewImageColumn you can set the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn.autosizemode.aspx">AutoSizeMode</a>[<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn.autosizemode.aspx" target="_blank" title="New Window">^</a>] or Width[^]

For further info read DataGridViewImageColumn [^] and see the example in the bottom of the page.
