Is it possible to load images top to bottom?

Question

Is it possible to load images top to bottom?

Is there a way to make browsers load images from the bottom to the top?

Imagine I have an extremely long image that takes 60 seconds to load. The content is designed to be read from bottom to top. Is there any trick I can use to ensure that the image loads from bottom to top, allowing users to start reading it even while it's still loading?

Thank you,

Here's a humorous "AAAAAND ITS GONE" meme related to this question.

Solution 1: (Derek's answer)

Flip the image and display it using -webkit-transform: scaleY(-1);

Solution 2 (aloisdg's answer)

Use BMP format, which prompts the browser to load the image in an "upwards" manner. While not optimal for saving large images, it presents a viable option as it eliminates the need to flip the image at the server-side.

Answer 1

Answer №1

Yes, it is possible. Simply utilize the BMP format, which stores images from the bottom up.

If you want to see an example of an image loading upwards, check out this link. (Remember to click on the button "Bitmap and .rle Images to view the sample.)

According to the information provided in the Bitmap file format from fileformat.info:

[Concerning file header structure] A positive Height value indicates a "bottom-up" bitmap with the origin at the lower-left corner. Conversely, a negative Height value signifies a "top-down" bitmap with the origin at the upper-left corner.

To improve loading speed, consider cutting the image into smaller slices on the server and loading them individually. This method allows for better control over content delivery.

Alternatively, you can rotate the image on the server before loading it normally. Then display it using CSS transform: rotate(-180deg).

In my opinion, advancements in technology such as Spdy, a replacement for Http, are enabling new possibilities.

Interestingly, some browsers like IE and Safari do not support Spdy due to its association with Google.

Check out this demo video: at around the 38-minute mark.

Furthermore, it may be necessary to divide your image into multiple parts, as suggested in another comment.

For those looking to enhance user experience by ensuring content is visible when images are loaded, consider using the jquery lazy load image plugin. Check out a demo here.

You can also opt for jpeg images instead of bmp files as they are generally smaller in size.

Here's a different approach that ensures compatibility with older browsers. The downside is that it may increase the size of your webpage and require more preparation. It's up to you to weigh the pros and cons based on your specific requirements.

Step 1: Edit the image in a graphics editor, flip it vertically, and save it as a new file for uploading to your website.

Step 2: Implementation details provided below...

JSFiddle: http://jsfiddle.net/abc123

Tools: Modernizer, JQuery

HTML:

<!--The original 'unflipped' image source-->
<img src="http://i62.tinypic.com/wratsj.jpg" id="bottomtotop">

CSS:

.flipped {
    transform: rotate(-180deg);
}

JS:

if (Modernizr.csstransforms) {
    // Replace the 'unflipped' image with the 'flipped' version.
    $("#bottomtotop").attr('src', 'http://i60.tinypic.com/2qajqqr.jpg').addClass('flipped');
}

To address the page size concern, you can simplify the JavaScript code by moving away from frameworks (e.g., using "document.getElementById('bottomtotop')" instead of "$('bottomtotop')"), but this will require significant time and effort.
