Some JPG images will resize, some made with Photoshop won't

[PetersOtto]

Hello everybody!

I have some problems with the image extension. Some images (.jpg) will resize, some won't. I made some test. I use Photoshop. When I use "export", yellow dont resize the image. When I use "save as", yellow resize the image.

As well I found an image in the internet that won't resize from yellow. When I open it with Photoshop and use "save as", yellow will resize it.

Is that a bug or is there an explanation for that behavior?

Best regards

Update: I use image extension VERSION = "0.8.18"

Could be a problem with image detection. Can you provide some example images to reproduce it?

[PetersOtto]

Yes, of course. The images with "export" in the filename do not work. I prepared this images with Photoshop export function.

On the following screenshot you will see the result on my LAMP-Server:

Let me know if you need more images.

Thank you for the bug report. I updated the core extension. There was a bug in the image detection. The JPG detection was written for images with the two most common JPG markers APP0/JFIF and APP1/Exif, but it ignored images with APP14/Adobe.

Should be fixed now, please try it out.

It works like a charm :) With my own images and with the images I found in the internet.

Thank you for help and for developing/maintaining YellowCMS.
