In this post, we will cover how to use a “Picture View” object to view pictures on a USB drive.

First, create a “Picture View” object. This can be found in the “Object” tab within the “Media” icon:
Within the “General” tab of the “Picture Display Object”, select “USB disk”:
Within the “Directory” section, you can specify the directory where the picture files are saved. The directory can be the one used for Video Input’s capture feature or Function Key’s screen hardcopy feature. The picture file saved in the external device can be immediately displayed. You can choose between saving in “Root Directory”, “Screen Hardcopy”, or “User-defined”. If you select “Dynamic-folder path”, you can designate a folder path by a local address. Please select a memory address that is empty and doesn’t overlap with other memory spaces:
In the “File selection” section, you have the option to (A) “Automatically display the newly generated image” if you would like to do so. You also have the option to (B) “Send notification when switching to a new picture”. When “Automatically display the newly generated image” is selected, the state of the designated address changes to On/Off when the new picture is displayed on HMI. (C) Furthermore, if you select “Specify a file from address”, the displayed picture is designated by a file name in a local address, and the toolbar will be hidden:
Within the “Outline” tab, you can select “Hide delete button” to remove it from the “Picture View” object. The option to “Display with original size when a picture size is smaller than the object size” is also available:
With your “Picture View” object configured, you will now be able to view pictures from a USB drive on your HMI.
The supported picture formats are: .jpg, .bmp, .gif, .png
