Submit images in a correct format and size.
Static (non-animated) image ads can be formatted as .JPEG, .PNG, or .GIF files. (For animated image ads such as Flash ads, see this policy for animated image ads.)
Image ad files must be 50K or smaller.
We'll show the following image ad sizes on content sites in the Google Network: (see examples)
Banner: 468 x 60
Square: 250 x 250
Small Square: 200 x 200

Skyscraper: 120 x 600

At the bottom of each image ad, we will include your URL and a Google link. To accommodate these elements, we will resize your images vertically by 11 or 22 pixels, depending on the image size option you've selected. (Please note that we will only resize your images, not crop them. All of your original image content, if approved, will remain intact and visible.) If you'd like to retain your image's original proportions, we recommend that you resize your images before you upload them. You may load images in the following sizes:
Banner: 468 x 49
Square: 250 x 239
Small Square: 200 x 200
Leaderboard: 728 x 79
Medium rectangle: 300 x 239

Animated image ads may not be resized. All animated ads must be submitted in the full standard format sizes. View policy
