Arduino Mega 2560 do not accept particular BPM image, Mega1280 does

In these cases only a WTF explains my feeling the most.

I'v made a program coding and debugghing on a Mega1280 , and then , since i needed more memory i took a 2560.
The problem with the 2560 was that the upload freezes with TX RX led blinking infinitely.

I'v checked some of my older "version" of the sketch, since i found the one that feeds the 2560. Well, the problem was due to those two BMP images:

WTF??? Why?? Becarrerful to BPM when using the 2560... Do you know why this was happening? If can be helpfull i can copy de HEX code for the BMP.

See this post I made earlier, it may be the answer to your problem:

Search your bitmap array for three or more 0x21 in a row.

Man... that's absurd!!
