I am new to this and am perplexed by the branding functionality of the web portal within SSRS. I understand that the brand package comprises 3 files one of which is the logo (LOGO.PNG) file in a zipped file. I copied an XBOX example to see how it works and that all worked a treat. I amended the package to include my own LOGO.PNG file (and a number of different images) to see how that would worked and I repeatedly get the error "The given key was not in the dictionary". If I change the LOGO.PNG image to the original XBOX example image, repackage and rereun then all is well.
What are the characteristics of the logo.file that must be adhered to? I am creating my image in photoshop as a 275 x 100 pixel image.
Surely it can't be that complicated - what might I be doing wrong?
