+Hey, Austin. Here's an example of a mail that is effected the issue:\r
+\r
+=E2=94=94=E2=94=AC=E2=95=B4multipart/alternative 896783 bytes\r
+ =E2=94=9C=E2=94=80=E2=95=B4text/plain 379 bytes\r
+ =E2=94=94=E2=94=AC=E2=95=B4multipart/related 892556 bytes\r
+ =E2=94=9C=E2=94=80=E2=95=B4text/html 1236 bytes\r
+ =E2=94=94=E2=94=80=E2=95=B4image/jpeg inline [photo.JPG] 890841 bytes\r
+\r
+The multipart/related part is initially hidden. Without Istvan's patch,\r
+there would be no button at all for the image/jpeg part, even when the\r
+multipart/related is exposed. With Istvan's patch the image/jpeg button\r
+is there, but without Mark's patch the button would actually reference\r
+the entire multipart/alternative part, instead of just the image/jpeg.\r
+If I tried to save the image/jpeg I would get the entire\r
+multipart/alternative mime structure in plain text.\r
+\r
+jamie.\r
