Bug: "File Mask" don't work as expected

Example: The pictures in an site are all recognised as JPG but they are all coded as WEBP So I will use the "File Mask" feature with the expression "[name].webp" But in the resulting ZIP all files named [name]-webp (with an "-" instead of ".") Tried some other special signs, all resultet in "-"

The file masking is used to rename filenames not extensions. Can you provide an example page with this JPG extension issue?

Do you mean all JPEG images are actually WebP with wrong file extensions?

For instance https://issuudownload.com/boschebikesystems/docs/boschae_hb2020_uk#lg=1&slide=5

I see https://image.isu.pub/200508114845-2a600b0beb5f2388992d42d368dbca81/jpg/page_6.jpg

The content type is 'image/jpeg'. Also the file includes JPEG magic code

JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1059x1497, components 3

Hmmm...

All picture are saved as JPG, the way I do it doesn't matter. But opened in XnViewMP the file properties shows the format WEBP. If you save the picture in Firefox (right click - save as) FF will automaticly prompt "save as *.webp", not JPG. Adobe Acrobat can't import WEBP (that was the first time i recognise this problem) and I have to convert all files in JPG / PNG first...

(and it is webp in HEX-code)

I see, I tested on Chrome and images are in fact JPEG. I can reproduce the issue on Firefox.

crazy behavior...

This extension uses the filename that the server returns when it can. So, for now, you can load the extension (the v2 directory) as a temporary add-on and change the code to force-rename as WebP.

https://github.com/belaviyo/save-images/blob/master/v2/data/ui/guess.js#L106

 .slice(0, 60)).join(extension);

to

.slice(0, 60)).join('.webp');

Alternatively use the extension on Chrome.

OK and many thanks!

For your information: I now tried a direct download with wget and the "JPG"-links to the files on the server (no Firefox used). The files are originally coded in webp.

Seems like the server returns WebP or JPG based on your IP address. It is not browser dependent.
