Can't change Icon of a DMG or air package in osx Mavericks

Hello I was hoping someone would be able to help. I'm attempting to make a fancy DMG for program I have developed for the company but keep coming up short when I try to change the icon when I view the contents of the folder/file.

I'm starting to wander whether something in Mavericks is simply stopping me from changing an icon on my custom dmg. To break it down.

Opened up the contents of the file
Drag - copy and paste the file over the icon in the top left (plus icon appears)
The file(s) fail to change correctly, 'paste' is greyed out when to copy and paste the icon into the position. A generic icon is replaced instead of what I copied over. Its a jpg image with "ICO" written in the bottom of graphic
I have the read write permissions (I published the file)

Is there a way of making this work? Please note I'm unfamiliar with working with terminal. I'm also open to programs which may give me the results I need that will overwrite the setting of that icon on that file.

Thanks,

Do you want to change the ICON of the DMG or the background-image for the window that opens when you open the DMG? – heiglandreas – 2014-09-24T14:57:23.810

Hello, the ICON. I've managed to change the BG image for the window. Thanks, – user3082874 – 2014-09-24T15:42:01.473

Result! This did the trick.

Go to "Get info" of the file's icon you want to change.
Open the image (PNG) of the image you are wanting to use in Preview (or a graphics editor)
"select" the image, and 'Copy' (Command-C) it
Go back to the "Get info" window and 'Paste' (Apple V) the image (the png you have selected) into the Preview Panel

This worked for me.

*Don't drag the file to the top left of "Get Info", it doesn't appear to work properly. OSX V 10.8.5 - Mavericks

When I want to change the ICON of a DMG-File I select the DMG-File in Finder, Hit CMD-I (or use the Information entry from the context-menu). Then select the Icon in the top-left corner of the Information-window and paste the relevant graphic into it.

When I want to change the Background-Image of a Finder-Window, I open up the window, I want to change, hit CMD-J and select "Image" as Background-Option. Then I paste the image into the now available Upload-Box. Set the other view-options you want to be available and close the DMG. That's it.

Hello Heiglandreas, I've managed to get that far and I mentioned in my query that I have got that far with dropping an image across/into the icon in the top left corner. I'm more stuck with why my computer is acting strangely when I try to do this... ie the image wont swap. Thanks for the answer anyway. I may have to get more into the nuts and bolts of this. – user3082874 – 2014-09-24T16:08:19.747

I'm assuming that you do have the access rights to change the file and that you have the file on a HFS+ formated drive. Can you change the icon of any othe file that lies right beneath the DMG? – heiglandreas – 2014-09-24T16:11:06.210

Yeah I assume so. In the bottom next to my name I have "Read & Write". Sorry what is a HFS+ formatted drive? No, I can't change the icon of any file. When I drag it over it swaps the image over for a generic icon with "ICO" written in the bottom. Any clues? – user3082874 – 2014-09-24T16:39:00.997

Is the DMG located on a server volume or on your local hard drive? If it's on a server volume do you connect via smb or afp? – heiglandreas – 2014-09-24T16:45:23.387

No that's fine. :-) Yes, i'm working on a Mac, i'm working on my Local Drive. – user3082874 – 2014-09-24T16:46:49.847

thats really strange as it should work that way. can you post a screenshot of the "Get Info" window? – heiglandreas – 2014-09-24T18:58:31.747

I need a rep of 10 plus to add images apparently. Much the same though I can't drag the image over the folder. It may be worth mentioning that I downloaded this. http://www.panic.com/blog/candybar-mountain-lion-and-beyond/

I wouldn't really say this solves my issue though. As I would like to be able to change the dmg icon without all this fussing over with 3rd party software. Thx
