Why are the thumbnail images not displaying on certain projects in the exported version of my Webflow portfolio site, specifically on mobile, when they appear fine in the Webflow preview?

There could be several reasons why thumbnail images may not be displaying on certain projects in the exported version of your Webflow portfolio site, specifically on mobile, even though they appear fine in the Webflow preview. Here are a few potential causes and solutions:

1. File path or naming issues: Make sure that the file paths and names of the thumbnail images are correct and match the references in your HTML or CMS collection. File names on your local machine are case-sensitive, so ensure that the filenames match exactly, including capitalization.

2. Image size and resolution: Check if the thumbnail images have been optimized for the web and are of an appropriate size and resolution. Large image file sizes can affect loading speed on mobile devices or cause them to be skipped entirely. Resize and compress your images to an optimal size without sacrificing quality.

3. CSS conflicts or errors: Inspect your CSS stylesheets and make sure there are no conflicting or overriding styles that may be affecting the display of the thumbnail images on mobile devices. Additionally, check for any CSS errors that could prevent the images from rendering correctly.

4. Responsive design issues: Ensure that the CSS styles and layout settings for your thumbnail images are properly configured for mobile devices. Double-check that the images are set to be responsive and have appropriate max-width properties to ensure they scale accordingly.

5. Cache-related issues: Sometimes, cached versions of your website or specific assets can lead to issues with image display. Clearing your browser cache or trying to access the website in an incognito or private browsing mode can help rule out any cache-related problems.

6. Network or hosting issues: If the issue persists, it could be related to your hosting provider or the network you are testing your website on. Try accessing your website on different devices, networks, or even through a mobile testing platform like BrowserStack, to see if the issue is specific to certain devices or connections.

If none of the solutions above resolve the problem, it might be necessary to share a live link to your website or more details about your setup for further investigation.
