Previously, it was mainly just pretty much poking around.
Numbers would generally be stored as 32-bit floats, so you could sometimes use RCO values as a hint and search the PRX for the value (eg, if XMB X position was offset by 130, you'd search PRXs for 130 in 32-bit float format).

Around firmware 5.00, Sony decided to try to make things harder by scrambling the values (they were loaded in 16-bit chunks), however, it's somewhat had the reverse effect as a "descrambler" can reassemble the 32-bit floats and single them out of the PRX file.


However, in your case, you're looking for an image, so this value hunting probably won't be of assistance to you at the moment.
Glad to be of help :)
