Jacking Points and Axle Stands

[collinsd70]

I know this subject has been heavily discussed but cannot find all info from using the search so any further advice would be appreciated thanks...

I am becoming increasingly worried about where i can rest the car on axle stands, i prefer to jack the car using the citroen scissor jack as it fits into the sill comfortably but am unable to find a secure place for axle stands on all 4 corners of the car.

Whilst changing my cambelt my dad used a normal car jack with a block of wood and placed it under the car (cant remember where exactly), basically it was weak and bend underneath the car and i was very angry.

Would someone be able to provide pictures of exactly where they can be placed securley, thanks in advance
