Including images in custom cls

Question

Let's say I have a custom class which is well recognized by pdflatex and in the right directory (texmf).

How could I integrate images (logos in headers) to be printed in each document using the class without copying them each time in the working directory or using absolute path (in order to be platform-independent) ?

I tried to put the images in the same directory of the class but pdflatex says they are not found as if it's searching in the current working directory of the file using the class.

Answer 1

It seems that indicate the graphics path with the command \graphicspath{} using relative path like ./foo/bar/ in the myclass.cls eliminate the trouble.
