Printing or exporting a map from ArcMap that contains data from Image Server displays the following error message:
"Image size is larger than server can serve."
The Image Server is being asked for an image larger than the Image Server is able to return. This happens most often when the Image Server data is placed on a larger page size, and/or in a large data frame, and/or printed or exported at a high resolution.
The maximum value should be a larger number than the maximum width and height of the map to be printed at the specified resolution. For example, a 24" x 36" map printed at 300 dpi will require at least 7200 x 10800 (24" x 300 by 36" by 300 dpi).
For optimal image print quality, set the output print quality to a minimum of 4; approximately 1 pixel is represented by 4 dots. On higher resolution printers, a value of 5 or greater is recommended for high image print quality.
