[TYPO3] How to get the path to an image

[Tomas Broeker]

Hi,

I am wondering right now how to get the path to an image and not just 
the filename.

I am using tt_address (and DAM - don't know exactly if one has to know 
that) an with every address set I am saving an image.

When I use

logo = TEXT
logo.field = image

to display the content of the field "image" (datatype tinyblob) in the 
tt_address table I only get the filename. So my question is: how do I 
get the path to that image? I can't use a fixed path as my images are in 
different folders. And actually the path should be stored somewhere 
because e.g. the extension sg_address is able to display the image in 
its content areas.

I would appreciate any hint or solution.

Regards
Thomas
