Downloading Images from Salesforce with Logged-in Session

Hi there,

I am working on a case where I need to download an image file through Salesforce using servlet.FileDownload. I have privilege to view or use Right-Click+Save-As to get the images, however it is slow in that way. I have also attempted to use HTTP Request activity, however it gets me a list of *.jpg.mht files.

Is there a smarter way that I could use something e.g. a HTTP Request to work with URLs such as

and get the actual image files?
