Get Image Using Http Request To Image url

Requirement : Get Image Using Http Request To  Image url

Here in this post  we will get the image by the help of image url using http request.

So we send a http request to the image url and get response body as blob later we convert blob into apex image or you can directly use blob to shoe image in your html or visualforce page by using html image tag

Steps to be followed : 

1.  Send Http request to image url and get image as a blob from response body
2.  display image on html page using  Html image tab

Step 1 : Sending http request 

HttpRequest imgreq = new HttpRequest();
imgreq.setmethod(‘GET’);
imgreq.setEndpoint(ld.Image_Url__c);
Http binding = new Http();
HttpResponse imgres = binding.send(imgreq);

// converting response as a blob

Blob imageblob = imgres.getBodyAsBlob();
image = EncodingUtil.Base64Encode(imageblob);

Step 1 : Display image on html using img tag

<img src="data:image/png;base64,'.base64_encode('your blob variable').'"/>
