michaelbennett3443 asked 5 years ago

I have both my ESP8266 and ESP32 Webservers running perfectly. I would like to know how to upload a background or icon image using spiffs to these servers. I have setup the ESP8266 Sketch Data Upload tool, I have created the data folder in the sketch and I have successfully upload the data to spiffs. My problem is creating the link from the html code to view the image on the server.

Any help will be appreciated.

Hi Michael.

Your image is not showing on your web server because you don’t make any request to the /img URL to serve the image.

I haven’t tried displaying images on an ESP32 web server, but here are some suggestions:

1. you can save the image on an external server and then include the image in an HTML tag by referring to its URL: <img src=”url”> w3schools.com/html/html_images.asp – see the “Images on another server” section

2. you can save the image in SPIFFS and then serve the image (as you’re doing in your code). The problem is that you don’t make any request to the image in your current code.

I think the best way to do it, is to rewrite your code to be compatible with the async web server. That way you can store both the image and the HTML file in SPIFFS if you want.

I think that if you include a tag that refers to the image name, the browser will make a request on that image, and you can respond back with the image file.

Useful resources: https://randomnerdtutorials.com/esp32-web-server-spiffs-spi-flash-file-system/
techtutorialsx.com/2018/08/24/esp32-http-web-server-serving-image-from-file-system/

I hope my explanation is clear.

Let me know if you need further help.

I’ve created an example that allows you to embedded images in a web server using base64 encoding.

The following code works with the ESP32/ESP8266. Take a look at line 31 to 34 where I embedded the images using the base64 encoding: https://gist.github.com/RuiSantosdotme/f9189a43ef89ca81bb9223971f02c5e6

You can use this free software to encode images to base64: https://www.base64-image.de

After uploading a image, click the “show code” button

And copy the highlighted part:

Does that method work for you?

Let me know your results
