Since Fotomoto references the low resolution images on your website, it doesn't know the resolution of your print-size images unless you tell it what they are. Once it knows the dimensions, it can display only the print sizes that your high resolution images can support (at a minimum of 150dpi).
For example, say your camera shoots images that are 5,568px x 3,712px. Divide each dimension by 150 (dpi) to get 37.12" x 24.75" - this is the maximum print size that we recommend you print. Fotomoto offers print sizes up to 180" x 30", but if you pass us the 5,568px x 3,712px dimensions as below, your customer will not be able to buy anything larger than 37.12" x 24.75" because none of those larger sizes will be displayed in our shopping cart Widget.
There are two ways to let Fotomoto know the resolution of the images on your site:
- Put the high resolution filename and file dimensions in to the img tag(s) on your web page, like this:
<img src="http://wvs.topleftpixel.com/photos/2013/06/ocad-lightning-storm_clouds_004.jpg"" data-pickup-filename="xyz.jpg" data-hires_width="2000" data-hires_height="3000" />
- If you're using the Fotomoto API, you can pass the high res file resolution to us via a call to our showWindow function. Please contact us for more information and samples.
