I need to import other picture file to an existing psd in Photoshop frequently. However, I do only know one complicated way to do this:
Open the file with Photoshop.
Windows->Float All in Windows
With Move select the imported file and drag it to the psd file with mouse.
This method require floating all in windows. Are there any other better method to import picture file in Photoshop CS5?
Hit File, then select Place. You can select files from the file manager and place them on the canvas.
