(keitai-l) Re: images on the scratchpad

Are you sure about that?  Because I'm fairly sure that gifs can
contain null bytes.  Fortunately, gifs also have a header that
tells them what the size of the image should be, so getImage()
can just read data until it's filled up the image.

Basically, I'm trying to say that I'm doing the same thing as
you, César, and it works on the emulator.

(Okay, I'm doing something a little more complicated, but
 similar.  I've created a RecordStore class which handles
 the location of the images in the scratchpad, and I then
 get them by type and id, but the resulting code is very
 similar.)

Later,
Blake.
