q_jpegmini tranformation problems
Hi,
I'm trying to use the jpegmini transformation on one of my images without luck. The following URL works:
But this gives me a error message stating that theres a error with the image:
Looking at the documentation (http://cloudinary.com/documentation/jpegmini_image_compression_addon) the URL looks correct, can you tell me what I'm doing wrong? The sample works.
BR,

Hi Andreas,
The JPEG mini Addon requires your URL to be signed, Only URLs with a valid signature that matches the requested image manipulation will be approved for on-the-fly image manipulation and delivery.
The
s--Q2hzuyWj--
part is the signature component, and is unique and is only valid to this specific image and for this specific account (the 'demo' account).
The signature is a base64 encoding of a SHA1 digest of your image public ID and transformation string concatenated with the account's API secret. The signature is automatically generated by Cloudinary's client integration SDKs (by setting thesign_url
parameter totrue
).For more information:

I'm seeing a similar problem. Even with
sign\_url
set totrue
, I'm getting an HTTP 420 response when trying to set jpegmini compression. Without jpegmini compression, image transformations work as expected.0 -
Nevermind. I didn't realize jpegmini was an add-on service. All better now.
