problem in image resizing
Have you tried .bmp? I think that does not use compression. It should be slightly greater than 100KB due to the header.

How to use an absolute scale with colormaps
Yes, just adjust the CLim property of the axes to the desired range. e.g. caxis([0 45]) will map the colors to 0-45 range.
