The invention discloses a synchronous test image display method and system, wherein the synchronous test image display method is applicable to execution in the synchronous test image display system. The synchronous test image display system comprises multiple mobile terminals, a server and a computing device. The method comprises that mobile terminals record images in a current test process, thus obtaining first video data; the first video data is coded, thus forming second video data; the second video is packaged, thus obtaining third video data; the third video data is uploaded to the server; the server obtains the name parameters of the mobile terminals from the uploaded third video data; the server generates multiple corresponding URL addresses according to the name parameters, wherein the URL addresses correspond to the third video data of the mobile terminals; the computing device accesses the URL addresses in multiple web pages; and the corresponding third video data is decoded and played, thus synchronously displaying the test images of the mobile terminals.
