what size of photo for an african visa?
 

hi there, went to get a few sets of passport sized photos done today ready for mass visa etc application ahead of my upcoming trip through Africa (London to Capetown) when I was told that some countries in Africa require a "visa" sized photos which is not the same as a passport sized photo. does anyone know from their recent travels if this is true for any African country? Haven't organised my exact route yet but am likely to roughly head south along the west coast and then back north again along the east coast, which covers a lot of countries. Any guidance would be great.

Thanks!
