The original grabs here were originally made using Tinderbox v2.3.4 and v2.4.0 and have been added to as new versions have changed the UI or new features have been added. Grabs are created with Ambrosia's Snaps Pro X with post-editing if required in GraphicConverter. Originally in JPG format, all newer grabs are in PNG format for better quality/compression.
The images are not stored in this TBX but are online at:
http://www.acrobatfaq.com/atbref5/images/ or in the /images/ sub folder of earlier aTbRef versions still online. The image folder can be downloaded for local use with an export of aTbRef. Should you wish to download the images for local use, please do so. I would ask though that - for bandwidth conservation - you don't hot-link to the online images apart from occasional references (e.g. blog items, etc.).
There is no index (as a web page) of the files in the above folder. The intent has to provide images of every dialog menu and window/view in the application and illustrate some of the more visual UI features.
