Hi
Use the PAPI! You could use the Searches object to navigate to the posting
that contains the image. For e.g.
CmsHttpContext cmsContext = CmsHttpContext.Current;
Posting myPosting =
cmsContext.Searches.GetByPath("/Channels/News/MyPostinng") as Posting;
if(myPosting!=null)
{
string url = ((ImagePlaceholder)myPosting.Placeholders["MyImage"].Url);
}
It would of course, be more efficient if used Searches.GetByGuid. But that's
only if you store the GUID of the posting somewhere.

Hi gg,
most likely rs is null.
That would make sense as you passed in an Url and a Path is not a Url.
So you can't use GetByPath with a Url - you need to pass in the Path of the
resource.
Cheers,
Stefan

Stream ResourceStream = rs.OpenReadStream();
cause i would like to resize the imageph content before the
displaying(of course there is other code following).
But when i open the site i get an error (Object reference not set to an
istance of an object) and the row "Stream ResourceStream =
rs.OpenReadStream();" is highlited.
My image is in the resouce gallery but i don't know how to pass the
path i can only pass the url.
Ther's another way?
