[Objective]Base on the principle of diversity and correlation, stimulate the group creativity by recommending pictures. [Context]The application context is group idea generation environment. [Methods] Base on text segmentation, webpage analysis technique and cosine similarity algorithm, the paper establishes a model of picture recommending system and raises Max Difference Algorithm (MDA) to select pictures for groups which in the process of creativity. [Results] This research proves the positive effect of picture recommendation system to group idea generation by an experiment method and proves the usability and accessibility of the system by survey. [Limitations]The Max Difference Algorithm is based on the text information around the pictures, and this information is often in difference with the pictures' content, so there are limitations on the MDA.[Conclusions] In the group idea generation process, group creativity performance can be improved by recommending pictures.
