In Strategy Web 9.3.1, when exporting a grid with custom images as thresholds to Excel 2007, the thresholds won't display correctly in Excel.
1) If the Document Properties: "Embed Images" and "Use live Excel charts" are selected, the threshold image enlarge to fit the size of the cell it's in, like shown below.

2) If the Document Properties: "Embed Images" checked and "Use embedded bitmaps" are selected, an error will show in place of the image, like shown below.

There is insufficient data to display the requested chart subtype for this report. Try using another chart subtype.

The linked image cannot be displayed.
