If the picture of the rooster, ps0402.psd, is not visible, choose Window > ps0402.psd
or click on the tab for that image at the top of the screen to make it the active
window. After coni rming that this is the active document, select Image > Image Size
to open the Image Size dialog box.
The Image Size dialog box appears.
Image size plays an important role when combining images.
The Image Size dialog box is divided into two main areas: Pixel Dimensions and
Document Size. Pixel Dimensions shows the number of pixels that make up the
image. For web graphics, the pixel dimensions are more relevant than the document's
actual printing size. Document Size shows the resolution information, as well as the
actual physical size of the image.
The most important factors for size and resolution of web images are the pixel dimensions and the
pixels per inch (ppi). If you are designing content for the Web, you should reference the top (Pixel
Dimensions) section of the Image Size dialog box. As a print designer, you should reference the
bottom (Document Size) section of the Image Size dialog box.

The image size of the rooster is 705 pixels by 681 pixels. At this size, the rooster is
taller than the barn, which would be apparent when you combine the two i les. While
this might work for an Attack of the Roosters horror movie, you're interested in making
the rooster smaller.

Make sure that the Resample Image and Constrain Proportions checkboxes are
both selected. In the Image Size dialog box, type 200 pixels for height in the
Pixel Dimensions portion at the top half of the dialog box. Press OK to apply the
transformation and close the Image Size dialog box.
