In SharePoint 2010, photos uploaded to the UPSA/MySite host generated thumbnails, the medium size being 96x96. In SharePoint 2013, it appears that this generated thumbnail is 72x72. We want to push these photos back into AD, which then syncs up with Office 365 to populate Lync, Outlook Address Book, etc. The default push pushes the LThumb into AD, which only stores the upper left 96x96 pixels. We’d like to have the MThumb push in, so I created a PS script which grabs the photos from the photo library, grabs the username, and stores it into that user object in AD. However, it only being 72x72, this is less than optimal for Outlook/Lync Address Book.
Is there any way to change the default generated thumbnail sizes in the MySite host? Or should I resort to downloading LThumb, resize to 96x96, and push to AD? I suppose in theory we could turn on Image Renditions.
