Click the thumbnail image of the required PSD file in the Extract panel. If an updated version of the PSD file becomes available on Creative Cloud after you open it, reload the PSD file in the Extract panel. To do so, click the name of the PSD file or click Reload PSD in pop-up menu on upper right. To go back to the thumbnail view and select a different file, click the Creative Cloud icon on the upper left of the panel.
To magnify the view and take a closer look at the design, change the zoom level at the top of the Extract panel or use Alt +/-. Use the Layers tab or the Layer Comp drop-down list to show or hide elements in the PSD file.
You are now all set to translate the PSD comp to a website.
