A client-server image display method comprising rendering a cursor on an image to be displayed according to either a server cursor rendering policy or a client cursor rendering policy, wherein according to the server cursor rendering policy the server is performing the rendering of a cursor on the displayed image and according to the client cursor rendering policy the client is performing the rendering of a cursor on the displayed image, the method executed at the server comprising the steps of: pre-configuring a process name set comprising a list of application program names that require the server cursor rendering policy, said application programs requiring a high accuracy in the location of the cursor on the displayed image; obtaining an image display instruction, wherein the image display instruction carries an image to be displayed; determining a name of a process associated with the image display instruction by querying a process space of the operating system, the process representing an application program that triggered the image display instruction; querying the process name set with the determined name of the process; determining that the cursor rendering policy is the server cursor rendering policy if the determined name of the process is comprised in the process name set and determining that the cursor rendering policy is the client cursor rendering policy if the determined name of the process is not comprised in the process name set; rendering a cursor on the image to be displayed if the determined cursor rendering policy is the server cursor rendering policy; and sending an image display message to a client, wherein the image display message comprises the image to be displayed, where the image to be displayed includes the rendered cursor when the determined cursor rendering policy is the server cursor rendering policy. pre-configuring a process name set comprising a list of application program names that require the server cursor rendering policy, said application programs requiring a high accuracy in the location of the cursor on the displayed image; obtaining an image display instruction, wherein the image display instruction carries an image to be displayed; determining a name of a process associated with the image display instruction by querying a process space of the operating system, the process representing an application program that triggered the image display instruction; querying the process name set with the determined name of the process; determining that the cursor rendering policy is the server cursor rendering policy if the determined name of the process is comprised in the process name set and determining that the cursor rendering policy is the client cursor rendering policy if the determined name of the process is not comprised in the process name set; rendering a cursor on the image to be displayed if the determined cursor rendering policy is the server cursor rendering policy; and sending an image display message to a client, wherein the image display message comprises the image to be displayed, where the image to be displayed includes the rendered cursor when the determined cursor rendering policy is the server cursor rendering policy.
