Urgent SEO Fix Needed - Robots.txt Issue

I'm in need of an SEO expert who can help address an urgent issue on my main website. Currently, there's a problem with the robots.txt file that's causing an unexpected block on all my image URLs. This is affecting my website's overall SEO performance and I'm seeking a specialist who can provide a swift and effective solution.

Key Requirements:
- Troubleshoot the existing robots.txt file
- Identify the cause of the image URL block
- Implement necessary fixes to ensure all image URLs are accessible by search engines

It is important to note that I have full access to my website's server and hosting account. However, I'm not well-versed in the technicalities of a robots.txt file hence, need an expert who can dive into this specific issue and provide a clean resolution.

Ideal Skills and Experience:
- Proven track record in SEO troubleshooting and problem-solving
- Proficient in identifying and rectifying robots.txt issues
- Strong understanding of website hosting and server access
- Excellent communication skills to explain the issue and solution clearly

Please note, while I'm looking for immediate support on this problem, I intend to manage the robots.txt file myself after it's been correctly set up.
