i want to make my own implementation to understand every thing better

this?

Yes.

can you point what should i improve in my code though?

Unfortunately, I don’t have time to review your code. Feel free to check the example projects, the documentation and the implementation of the libraries for inspiration.

could you brief this process?

I wouldn’t recommend it, especially if you’re in a hurry, it’s quite a complex subject. But if you really want to, then I would suggest:

I’m happy to help with any specific questions that you might have after doing this.

I’m not sure what’s happening here, if @Severin doesn’t know then maybe it would be better to create a new topic for that so others can see it.

@Severin
i have implmeneted my logic based on this :star2: sdk/src/canisters/frontend/ic-certified-assets at master ¡ dfinity/sdk ¡ GitHub

now i get tinvalid response hashes even though image is uploaded successfully:
https://esygv-biaaa-aaaak-ak2va-cai.icp0.io
https://zcs7y-5iaaa-aaaam-adxfq-cai.icp0.io/file-image-1.jpg

Response verification failed: The wildcard expression path provided by the "IC-Certificate" response header (["http_expr", "<*>"]) is valid for the request path ("/file-image-1.jpg"), but was not found in the tree

To me this reads like you do the right thing in http_request, but you don’t set the /http_expr/<*> value in the cert tree when uploading the files

i am able to upload max 2 mb size of files at the moment , how can we store greater than 2 mb file size ?

You have to upload files in chunks. In the canister you can then stitch the pieces back together
