Before the ubiquity of Adobe Photoshop or the organizational structures of Google Photos, the Windows 95/98 ecosystem required efficient tools for viewing the burgeoning number of digital images, GIFs, and early JPEGs. ACD Systems released ACDSee 2.4 in 1998 as an incremental but significant upgrade. Unlike its predecessor, version 2.4 offered improved stability, broader format support, and a more intuitive drag-drop workflow.
The primary selling point of ACDSee 2.4 was speed. In the late 90s, the default Windows image viewers were often sluggish or incapable of opening newer file formats efficiently.
