What is the largest image that ThumbsPlus can load?
Except on Windows 3.1, where the maximum is 16 Mb, there is no fixed limit – the largest file that ThumbsPlus can load on your machine is dependent on the amount of available memory in it. ThumbsPlus does use virtual memory for loading images, so it may help to increase the amount of swap space available. Be aware that images which are compressed will take much more RAM than disk space; they are decompressed to load and display. In general, you can compute the memory required based on the dimensions and color depth of the image. The area of the image times the bytes per pixel will give a good estimate of the memory required. For example, a 1000 x 1000 24-bit image would require 1000 x 1000 x 3 = 3,000,000 bytes (24 bits per pixel = 3 bytes per pixel).
