I want the flow to be : A user uploads an image → It gets stored in a canister → A user can visit a url and see that image. I do know about cancan but its a bit complicated. ---

Static images: use “asset” canisters (see the SDK quick start) User-generated images: chunk image blobs in the client and call custom canister methods with those blobs as arguments (see CanCan’s source) ---

@anon74414410 another dev with the same question on uploading blobs. I think I’ve made my point so I’ll stop @'ing you on stuff now. My apologies again 😅 ---

Hi guys, I’m running into this - since I would like users of my app to upload images - and a lot of questions of popping up: - What is the best architecture to support this: is it recommended to have a separate canister just for hosting the uploaded images ? - Feels like most apps are going to need such a feature: is there any recent working guide/example of uploading images to a canister ? (I have a react + motoko app). @pattad Would you say you’re example is still up to date ? Are you still using it ? Thanks ! ---

yes I’m still using it and its working. However, please check the latest Api documentation of Motoko to check its status. ---

In the end I simply stored images as a base64 string. It appears to work quite nicely, but I haven’t tried in production yet. Anyway, thanks for your help 🙂 ---

If you’re going with base64, tools like [base64imageconverter.com](http://base64imageconverter.com) make it easy to test and prepare images before storing them in a canister.
