Callimachus supports SVG, GIF, ICO, PNG, and JPEG image formats. Use the upload button in a the folder view or drag and drop the image onto the folder view listing.

JPEG photo files support server side resizing for network optimization. These pragmas return an image with the same proportions as the original, but the entire image has been resized so that either the width or height is one of the corresponding pixel lengths (the smaller dimension).

Pragma Description
?large A photo with a size of at least 1080 pixels in both dimensions
?medium A photo with a size of at least 480 pixels in both dimensions
?small A photo with a size of at least 240 pixels in both dimensions
?thumbnail A photo with a size of at least 64 pixels in both dimensions

These pragmas, which are only available to JPEG files hosted on Callimachus, can be used with the picture and source tags.

Only Chrome 38 and Firefox 33 support the picture element at this time.

<picture>
    <source media="(min-width: 1080px)" srcset="photo.jpeg?large" />
    <source media="(min-width: 480px)" srcset="photo.jpeg?medium" />
    <img class="img-responsive" src="photo.jpeg?small" />
</picture>
