Why do some of the images not show up on screen after being compressed with the Webflow tool, and why do I have to delete them and then replace them in order to fix the issue?

There could be several reasons why some images may not show up on the screen after being compressed with the Webflow tool. Here are a few possibilities:

1. File Format: Double-check the file format of the images that aren't showing up. Webflow supports popular file formats like JPEG, PNG, and GIF. If the images are in an unsupported format or corrupted, they may not display correctly. Converting the images to a supported format before compressing them can help resolve this issue.

2. Compression Settings: When compressing images with the Webflow tool, it's important to pay attention to the compression settings. If the compression level is too high, it can result in a significant loss of image quality, leading to images not displaying correctly. Adjust the compression settings to strike a balance between compression and image quality.

3. Caching: The issue of images not showing up could be related to caching. Browsers often cache website files, including images, to improve loading times. If an image was previously loaded on a page before compression, the browser may still be serving the cached version, which could be causing the image to not show up. Clearing your browser cache or doing a hard refresh (Ctrl+F5 or Cmd+Shift+R) can help resolve this problem.

Regarding why deleting and replacing the images fixes the issue, it's likely because when you delete an image and replace it with a new one, you're essentially forcing the browser to download the image again. This bypasses any caching issues and ensures that the newly compressed image is loaded on the page. However, keep in mind that this may not always be necessary, and it's generally preferable to address the root cause of the issue rather than resorting to deleting and replacing images.

In addition, remember to thoroughly test your website on different devices and browsers after compressing images to ensure that they display correctly. It's also a good practice to keep backups of your original images in case you need to revert or re-upload them.
