I didn't found brighter images, I will explain what I did.
I went to the
PDS (Planetary Data Systems) Geosciences Node site, chose the mission (MER) on the Quick
Links on the left, and then the
The Geosciences Node MER online data
repository and then I chose the "Pancam Science Radiometrically Calibrated Image RDRs" from Spirit,
here.
After choosing the "Data" directory I chose the Sols I wanted (621 and 624) and downloaded the images I wanted.
After that I used
IMG2PNG, a program that converts the IMG files to PNG files.
IMG2PNG uses the radiometric correction data embedded on the IMG file to correct the photo, and it also has the possibility of increasing the
brightness of the images.
I created two versions, one that looked "normal" (using the -s20 parameter of IMG2PNG) and then I created another, brighter, version (using -s50).
Then I joined these two images as layers on Paint Shop Pro (but I could have done it in any other program, like Photoshop or The Gimp), the brighter
image over the normal image but with only a 50% visibility, to make the normal looking image appear on the brighter areas (there were many white
areas) of the brighter image. The result was what you saw.
This is what the brighter image looks like.
And this is the normal image.

And it does look less like a creature from the other angle and the brightness turned up. Where do you find these
brighter images that you combined to make the grayscales? That's a pretty good trick if you want to enhance some detail.
