Doctor Who screen capture plea/request

[jedichad]

I'm looking for good, quality screen captures from "The Sensorites", "The Reign of Terror", "Planet of Giants", "The Time Meddler" and "The Ark". The ones availabe at the DW Image Archive are so murky and grainy. If somebody can help out or point me where there might already be a batch, it would be a tremendous help!

Thanks in advance!!
