Images in the header of reports

Feb 2, 2011 at 12:52 PM

On one of the reports we've created on SSRS 2008 there are logo images on each side of the report, when looking at the report using Reporting Services own web interface the images are scaled properly to fit the report. However when looking at it using the "helloworld.php" they do not scale at all. So half of the picture is cut off. Is there a way through the SDK to specify the dimensions of the pictures ? 

Also I was wondering about the image files that is downloaded to the webserver every time a report is being viewed. As we roll this out it will get a lot of traffic and if those images just keeps building up it will quickly eat away our disk space. So is there a function in the SDK for cleaning this up or do I have to write this myself ?
