You may want to upload an image to be able to post a graphical ad, but would like to make sure it meets the optimal sizing criteria. It is recommended that the graphic file size be no larger than 8 MB, and the dimensions should be 1000 pixels wide by 670 pixels tall. You need to use some a photo editing program in order to make the changes to any graphic that you receive.
If using Microsoft Paint:
Open the image. The size of the image in pixels and KB will be listed on the bottom toolbar.
Select the Resize tool. You can increase or reduce the size of the image by pixels. We recommend you click the checkbox "Maintain Aspect Ratio" so the image does not become distorted.
Enter 1000 pixels as the width and 670 pixels as the height, and click OK.
Then, save the image as a .jpg, and the updated size of the image will appear on the screen.
Adjust as needed.
If using Adobe Elements:
Open the image.
From the top toolbar, click on "Image", then "Resize", and then "Image Size".
Enter 1000 pixels as the width and 670 pixels as the height, and click OK.
Save the image as a .jpg.
To complete the saving process, a window titled "JPEG Options" will appear.
Under "Image Options", move the gradient between "small file" and "large file" to either increase or reduce the size of the image, and click OK.
Once your image is resized, you can follow the steps here to upload it to your ad journal.
