Why is a thick gray line being added to some images in Webflow, even though there is no sign of it in the designer?

If you're experiencing a thick gray line being added to some images in Webflow, even though it's not visible in the designer, there could be a few potential reasons for this issue. Let's explore some of the possible causes and solutions:

1. Border or outline applied to the image: Check if you have applied a border or outline to the image element in the Webflow Designer. Sometimes, a thin border or outline may not be visible while designing, but it can appear thicker or change color in certain circumstances. To resolve this, navigate to the Style panel and make sure the border and outline properties are set to none or transparent.

2. Box-shadow effect: Another possibility is that a box-shadow effect is being applied to the image element, which could be causing the gray line. Box shadows can have various properties such as color, size, and blur, and it's possible that the values set for the box shadow are resulting in a thick gray line. Double-check the Style panel and make sure any box shadow is properly configured to match your design intentions.

3. Compression artifacts: If your image has compression artifacts, they can sometimes appear as thick gray lines around the edges when displayed on certain devices or screen resolutions. These artifacts can occur due to image compression settings, particularly if the image has been resized or exported with lower quality. To mitigate this, try saving or exporting the image with higher quality settings and verify if the issue persists.

4. Browser rendering or cache issue: It's also worth considering the possibility that the gray line might be a result of how the browser is rendering the image or cache issues. To address this, try clearing your browser cache, disable any browser extensions that might affect the rendering, or open your website in different browsers to see if the issue persists across all of them.

5. Image format or transparency: Depending on the image format used (such as PNG), some transparency-related properties might be causing the gray line to appear. If possible, try saving or exporting the image in a different format (e.g., JPEG) and see if that resolves the issue.

If none of these solutions resolve the problem, it would be helpful to provide more specific details or share the affected website or project in the Webflow Designer's read-only link. This will allow for a more accurate diagnosis and provide a better understanding of the issue.
