Read Protected PIC

The whole point of write protecting them is that you can't recover the ROM contents. Well, you can always strip off the plastic and image the bits, but that's a whole lot more expensive than writing your own code...
Won't work on most PICs, which use EPROM, EEPROM, or Flash memory cells. There's no optically visible difference between cells storing a 0 vs. a 1.
Not by looking at them, but you can optically or eddy current probe them:

'Imaging', does not imply visual. You can get the data with a SEM, but the cost is typically perhaps $20000+. You also then have to work out where each 'bit' resides in the physical memory structure.
