Usage by AOL
The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such images in the ART format to achieve faster downloads on the slower dialup connections that were prevalent in those days.
Software support for ART
The Graphic Workshop Professional software from Alchemy Mindworks Corp. supports ART files.[5] (With later versions of the Graphic Workshop Professional software, an ART plugin from Alchemy Mindworks is required for this support.)[5] For the Windows 2000 platform, Microsoft released the AOL Image Support Update which added support for ART images.[6] As of June 2006 the Internet Explorer browser no longer supported ART files when Microsoft released a security update. [7] Among other things, this update removed support for ART files from the Internet Explorer browser in order to help prevent issues where invalid ART data could cause the Internet Explorer software to unexpectedly quit.[7] An ART file that is opened with the AOL picture viewer can be saved as another file type. Software Mfg. Delcam (a subsidiary of Autodesk) has a product called Artcam which uses the ART file extension to create CAD/CAM files.
