[cross-project-issues-dev] Couple of questions on 'branding'

[David M Williams <david_williams@xxxxxxxxxx>]

Sorry for these basic "user questions", but am hoping for some quick 
answers to get in this release. 

1. I've seen several cases of an 'image' attribute in feature elements. 
But I can find no documentation for it. 
Is that just some old thing that's currently ignored? 
Or is it an undocumented function we should all mimic? 

<feature
      id="org.eclipse.platform"
      label="%featureName"
      version="3.5.0.qualifier"
      provider-name="%providerName"
      image="eclipse_update_120.jpg">

2. I've seen a number of places where both a 'gif' and a 'png' is 
provided. 
Why both? 
Do we have to provide both formats? 
Or is 'png' enough?

Thanks,
