How do I resize my images using ImageShack?
Select an image to upload, then checkmark the box next to “Resize Image?” Finally, select a new size from the drop down menu and click the “host it!” button. Your image will resample and resize based on the dimensions you selected. However, you cannot resize an image to be bigger than the actual source image that you upload. Your image’s original proportions will be kept. Flash and Video cannot be resized.
