Hi Turbo,

I did the change and replaced the image. The image could be loaded to the gps, but would not display.

I think the problem with the original file is at the end, not the beginning, because

[1] I checked the original 660 bin file from which the logo bin file was carved out, and it has 00 FC 03 00;
[2] When I loaded that logo bin file, I did get the garbled image displayed;
[3] The size of a normal 480x272 image is smaller than the one reported by GIR_Editor of the garbled logo: The reported size of the good image is 261120, while the internal one is 269249 -- note the former is 0x03FC00, and the latter 0x041BC1.

So it seems that 03FC00 was the real/correct size; the problem is that the actual image was somehow messed up. So what I really need, I think, is a "template" that is of size 03FC00 and of image dimension of 480x272; the actual image does not matter as it will be replaced,but the size is important.

If you could teach me on how to make such a template (as I still have no clue about the layout of the logo bin file), I should be all set.

Thanks again.

Sean
