Hello:
Some details on ED768 are here:
Lost Bombers - World War II Lost Bombers
There is also a wide variety of documents available online for 467 Squadron.
Go here:

On the screen that results, find the box called "Keywords (or name)", and type in 467 Squadron, then click the large "Search" button at the bottom of the page.
On the screen which results, click the uppermost of the two "display" buttons.
The screen which then appears is called "Display item search results". Click the "Digitised images first" button.
All of the (many) documents which have been scanned in by National Archives of Australia staff will then be available to you. The one you want most is "Unit history of number 467 Squadron - December 1942 to October 1945". Click the "View Digital Copy" link.
There are 1,238 (!) pages in this file. It appears to have been scanned in reverse order - page 1238 refers to the squadron being new, and is for December 1942. When reading the pages, ensure you have clicked the "Enlarge" button at the very top of the page, otherwise the image may be too small.
The loss of ED768 appears on page 1085 of the file. You should be able to trace all other details of the Ops your Grandfather went on by scrolling back in time, ie. start at page 1085 and enter progressively larger numbers. Note that postings onto and off the squadron are also recorded, so you should be able to determine when your Grandfather was first posted in.
Crew photos are sadly very rare.
The other digital documents on the Archives site may give you some flavour of life on the squadron.
You should also note from the Lost Bombers site that Sgt. Egan was on the run for a month before finally being captured - that may have been the reason for his mistreatment.
