Wrong Mime Type of product images

[borislav123]

Hello, all. We are using this good script in a website but we detected an issue.

1 . Product image - tyre - /used in product page - example - [https://diana-ltd.com/tire?46586] ) - Right click on the image - Open image in new tab / https://diana-ltd.com/cache/image/b65336a9b76813cc4bdf2f11be923bb0/AHrz-LM005.png

2. Image test - with this tool - [https://jimpl.com] - (https://jimpl.com/results/hMrpfTRZr3ZXdqU6NCaBAcX6?target=exif) - when you put your image URL path - / https://diana-ltd.com/cache/image/b65336a9b76813cc4bdf2f11be923bb0/AHrz-LM005.png /

3. Result - image is PNG but we send to the browser Mime Type - image/jpeg .

How to make mime type to be proper - to become image/png.?

Thank you.

The image at https://diana-ltd.com/thumbs/files/models/3531/220207-134553-Uniroyal_RainExpert_5_ProductPicture_30.png is PNG (with transparency). The image at https://diana-ltd.com/cache/image/4c2bdb024973262e66ce8544f88cd327/220207-134553-Uniroyal_RainExpert_5_ProductPicture_30.png is a JPEG (doesn't matter what the filename is called).

Actually you have some interesting URL rewriting going on -- https://diana-ltd.com/cache/image/4c2bdb024973262e66ce8544f88cd327/220207-134553-Uniroyal_RainExpert_5_ProductPicture_30.jpg also works, gives you the identical JPEG image as the above .png link. In fact everything after the hash is ignored, so you can get https://diana-ltd.com/cache/image/4c2bdb024973262e66ce8544f88cd327/ and it's still the same JPEG image.

Hello, @JamesHeinrich . Thank you for your explanation. I think I got it.

But then why the picture looks like this -

and not like this -

When I right click on the image - Open image in new tab ....

Thank you.

The server isn't returning any MIME type with the request, so the browser displays it as text.

print_r(get_headers('https://diana-ltd.com/cache/image/4c2bdb024973262e66ce8544f88cd327/220207-134553-Uniroyal_RainExpert_5_ProductPicture_30.png'));

Thank you, so much, @JamesHeinrich .

How it could be solved?

[JamesHeinrich]

I have no idea. It's possibly something related to CloudFlare (which I have no experience with). It doesn't appear to be related to phpThumb.

Got it. Thank you.
