Convert blob to images and save it to local folder - Apex - salesforce

Question

I'm able to read blob from the richtext field now need to save it as .jgp/png into my local folder
Matcher imgMatcher = Pattern.compile( '<img(.+?)>' ).matcher(con.Photo__c);
String imageURL = imageTag.substringBetween( ' src="', '"' );
String decodedURL = imageURL.unescapeHtml4();
PageReference page = new PageReference( decodedURL );
Blob bodyBlob = page.getContent();
//something like this
File file=new File('c://myimages');
image img=new image(bodyBlob);
img.fomrat='jpg';
img.title='myphoto';
file.save(img);
so it stores as image in my local folder. is this possible using apex(salesforce)

Answer 1

Salesforce cannot write to your file system. You have a few options, you can save to an Attachment record or Document record and download it from there, or you can expose the file through a visualforce page that lets you download the file as an attachment if you dont want to have it stored in salesforce at all. something along the lines of:
<apex:page contentType="img/jpg" extensions="xxx">{!image}</apex:page>

Answer 2

This is how i achieved, once saved to salesforce folder from there i downloaded the images, hope it helps someone.
Matcher imgMatcher = Pattern.compile( '<img(.+?)>' ).matcher(con.Photo__c);
String imageURL = imageTag.substringBetween( ' src="', '"' );
String decodedURL = imageURL.unescapeHtml4();
PageReference page = new PageReference( decodedURL );
Blob bodyBlob = page.getContent();
Document doc=new Document();
doc.Body=bodyBlob;
doc.FolderId='salesforce folder Id';
doc.Name=con.name;
doc.Type='jpg';
Insert doc;
