It seems some of the picture hosts have quit working or don't work reliably. Which site(s) would y'all suggest that might be long term reliable?

A lot of my research time has been trying to find all/most of the parts required for my work to be done. Such as fuel related hoses, o-rings, filters, etc...
The lists posted seem to be not quite complete with part #'s, o-ring sizes, etc.
What is the suggested way to post those lists that have been found through lengthy searching?

Is there a preferred site for getting into the Mercedes epc parts list that are accurate based on the vehicles serial #? It seems some sites allow access if you are a paid member. One Australian site appears to provide that link. The Russian site seems to be not complete.
