How can I change initlogo.rle 800x480.

I can not change initlogo.rle 1.46MB in size taplet. initlogo.rle 1.46 MB (1,536,000 bytes)
I use photoshop & to565 size to 1.1MB, and placed in a modified fw.
It does not show up and jump. bootanimetion.
I need to be able to use initlogo.rle in other sizes.





Thank you.:confused:
